remove many test-cases related to tcl_precision

TIP 488: Remove tcl_precision
Remove stub entries for Tcl_EvalObj()/Tcl_GlobalEvalObj(). Since those functions are actually macro's translating to Tcl_EvalObjEx(), those stub entries don't serve any purpose any more.

-1. Compression algorithm (deflate)
-
-The deflation algorithm used by gzip (also zip and zlib) is a variation of
-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
-the input data.  The second occurrence of a string is replaced by a
-pointer to the previous string, in the form of a pair (distance,
-length).  Distances are limited to 32K bytes, and lengths are limited
-to 258 bytes. When a string does not occur anywhere in the previous
-32K bytes, it is emitted as a sequence of literal bytes.  (In this
-description, `string' must be taken as an arbitrary sequence of bytes,
-and is not restricted to printable characters.)
-
-Literals or match lengths are compressed with one Huffman tree, and
-match distances are compressed with another tree. The trees are stored
-in a compact form at the start of each block. The blocks can have any
-size (except that the compressed data for one block must fit in
-available memory). A block is terminated when deflate() determines that
-it would be useful to start another block with fresh trees. (This is
-somewhat similar to the behavior of LZW-based _compress_.)
-
-Duplicated strings are found using a hash table. All input strings of
-length 3 are inserted in the hash table. A hash index is computed for
-the next 3 bytes. If the hash chain for this index is not empty, all
-strings in the chain are compared with the current input string, and
-the longest match is selected.
-
-The hash chains are searched starting with the most recent strings, to
-favor small distances and thus take advantage of the Huffman encoding.
-The hash chains are singly linked. There are no deletions from the
-hash chains, the algorithm simply discards matches that are too old.
-
-To avoid a worst-case situation, very long hash chains are arbitrarily
-truncated at a certain length, determined by a runtime option (level
-parameter of deflateInit). So deflate() does not always find the longest
-possible match but generally finds a match which is long enough.
-
-deflate() also defers the selection of matches with a lazy evaluation
-mechanism. After a match of length N has been found, deflate() searches for
-a longer match at the next input byte. If a longer match is found, the
-previous match is truncated to a length of one (thus producing a single
-literal byte) and the process of lazy evaluation begins again. Otherwise,
-the original match is kept, and the next match search is attempted only N
-steps later.
-
-The lazy match evaluation is also subject to a runtime parameter. If
-the current match is long enough, deflate() reduces the search for a longer
-match, thus speeding up the whole process. If compression ratio is more
-important than speed, deflate() attempts a complete second search even if
-the first match is already long enough.
-
-The lazy match evaluation is not performed for the fastest compression
-modes (level parameter 1 to 3). For these fast modes, new strings
-are inserted in the hash table only when no match was found, or
-when the match is not too long. This degrades the compression ratio
-but saves time since there are both fewer insertions and fewer searches.
-
-
-2. Decompression algorithm (inflate)
-
-2.1 Introduction
-
-The key question is how to represent a Huffman code (or any prefix code) so
-that you can decode fast.  The most important characteristic is that shorter
-codes are much more common than longer codes, so pay attention to decoding the
-short codes fast, and let the long codes take longer to decode.
-
-inflate() sets up a first level table that covers some number of bits of
-input less than the length of longest code.  It gets that many bits from the
-stream, and looks it up in the table.  The table will tell if the next
-code is that many bits or less and how many, and if it is, it will tell
-the value, else it will point to the next level table for which inflate()
-grabs more bits and tries to decode a longer code.
-
-How many bits to make the first lookup is a tradeoff between the time it
-takes to decode and the time it takes to build the table.  If building the
-table took no time (and if you had infinite memory), then there would only
-be a first level table to cover all the way to the longest code.  However,
-building the table ends up taking a lot longer for more bits since short
-codes are replicated many times in such a table.  What inflate() does is
-simply to make the number of bits in the first table a variable, and  then
-to set that variable for the maximum speed.
-
-For inflate, which has 286 possible codes for the literal/length tree, the size
-of the first table is nine bits.  Also the distance trees have 30 possible
-values, and the size of the first table is six bits.  Note that for each of
-those cases, the table ended up one bit longer than the ``average'' code
-length, i.e. the code length of an approximately flat code which would be a
-little more than eight bits for 286 symbols and a little less than five bits
-for 30 symbols.
-
-
-2.2 More details on the inflate table lookup
-
-Ok, you want to know what this cleverly obfuscated inflate tree actually
-looks like.  You are correct that it's not a Huffman tree.  It is simply a
-lookup table for the first, let's say, nine bits of a Huffman symbol.  The
-symbol could be as short as one bit or as long as 15 bits.  If a particular
-symbol is shorter than nine bits, then that symbol's translation is duplicated
-in all those entries that start with that symbol's bits.  For example, if the
-symbol is four bits, then it's duplicated 32 times in a nine-bit table.  If a
-symbol is nine bits long, it appears in the table once.
-
-If the symbol is longer than nine bits, then that entry in the table points
-to another similar table for the remaining bits.  Again, there are duplicated
-entries as needed.  The idea is that most of the time the symbol will be short
-and there will only be one table look up.  (That's whole idea behind data
-compression in the first place.)  For the less frequent long symbols, there
-will be two lookups.  If you had a compression method with really long
-symbols, you could have as many levels of lookups as is efficient.  For
-inflate, two is enough.
-
-So a table entry either points to another table (in which case nine bits in
-the above example are gobbled), or it contains the translation for the symbol
-and the number of bits to gobble.  Then you start again with the next
-ungobbled bit.
-
-You may wonder: why not just have one lookup table for how ever many bits the
-longest symbol is?  The reason is that if you do that, you end up spending
-more time filling in duplicate symbol entries than you do actually decoding.
-At least for deflate's output that generates new trees every several 10's of
-kbytes.  You can imagine that filling in a 2^15 entry table for a 15-bit code
-would take too long if you're only decoding several thousand symbols.  At the
-other extreme, you could make a new table for every bit in the code.  In fact,
-that's essentially a Huffman tree.  But then you spend too much time
-traversing the tree while decoding, even for short symbols.
-
-So the number of bits for the first lookup table is a trade of the time to
-fill out the table vs. the time spent looking at the second level and above of
-the table.
-
-Here is an example, scaled down:
-
-The code being decoded, with 10 symbols, from 1 to 6 bits long:
-
-A: 0
-B: 10
-C: 1100
-D: 11010
-E: 11011
-F: 11100
-G: 11101
-H: 11110
-I: 111110
-J: 111111
-
-Let's make the first table three bits long (eight entries):
-
-000: A,1
-001: A,1
-010: A,1
-011: A,1
-100: B,2
-101: B,2
-110: -> table X (gobble 3 bits)
-111: -> table Y (gobble 3 bits)
-
-Each entry is what the bits decode as and how many bits that is, i.e. how
-many bits to gobble.  Or the entry points to another table, with the number of
-bits to gobble implicit in the size of the table.
-
-Table X is two bits long since the longest code starting with 110 is five bits
-long:
-
-00: C,1
-01: C,1
-10: D,2
-11: E,2
-
-Table Y is three bits long since the longest code starting with 111 is six
-bits long:
-
-000: F,2
-001: F,2
-010: G,2
-011: G,2
-100: H,2
-101: H,2

-So what we have here are three tables with a total of 20 entries that had to
-be constructed.  That's compared to 64 entries for a single table.  Or
-compared to 16 entries for a Huffman tree (six two entry tables and one four
-entry table).  Assuming that the code ideally represents the probability of
-the symbols, it takes on the average 1.25 lookups per symbol.  That's compared
-to one lookup for the single table, or 1.66 lookups per symbol for the
-Huffman tree.
-
-There, I think that gives you a picture of what's going on.  For inflate, the
-meaning of a particular symbol is often more than just a letter.  It can be a
-byte (a "literal"), or it can be either a length or a distance which
-indicates a base value and a number of bits to fetch after the code that is
-added to the base value.  Or it might be the special end-of-block code.  The
-data structures created in inftrees.c try to encode all that information
-compactly in the tables.

-Abstract
-
-   This specification defines a lossless compressed data format.  The
-   data can be produced or consumed, even for an arbitrarily long
-   sequentially presented input data stream, using only an a priori
-   bounded amount of intermediate storage.  The format presently uses
-   the DEFLATE compression method but can be easily extended to use
-   other compression methods.  It can be implemented readily in a manner
-   not covered by patents.  This specification also defines the ADLER-32
-   checksum (an extension and improvement of the Fletcher checksum),
-   used for detection of data corruption, and provides an algorithm for
-   computing it.

-1. Introduction
-
-   1.1. Purpose
-
-      The purpose of this specification is to define a lossless
-      compressed data format that:
-
-          * Is independent of CPU type, operating system, file system,
-            and character set, and hence can be used for interchange;
-
-          * Can be produced or consumed, even for an arbitrarily long
-            sequentially presented input data stream, using only an a
-            priori bounded amount of intermediate storage, and hence can
-            be used in data communications or similar structures such as
-            Unix filters;
-
-          * Can use a number of different compression methods;
-
-          * Can be implemented readily in a manner not covered by
-            patents, and hence can be practiced freely.
-
-      The data format defined by this specification does not attempt to
-      allow random access to compressed data.

-RFC 1950       ZLIB Compressed Data Format Specification        May 1996
-
-
-   1.2. Intended audience
-
-      This specification is intended for use by implementors of software
-      to compress data into zlib format and/or decompress data from zlib
-      format.
-
-      The text of the specification assumes a basic background in
-      programming at the level of bits and other primitive data
-      representations.
-
-   1.3. Scope
-
-      The specification specifies a compressed data format that can be
-      used for in-memory compression of a sequence of arbitrary bytes.
-
-   1.4. Compliance
-
-      Unless otherwise indicated below, a compliant decompressor must be
-      able to accept and decompress any data set that conforms to all
-      the specifications presented here; a compliant compressor must
-      produce data sets that conform to all the specifications presented
-      here.
-
-   1.5.  Definitions of terms and conventions used
-
-      byte: 8 bits stored or transmitted as a unit (same as an octet).
-      (For this specification, a byte is exactly 8 bits, even on
-      machines which store a character on a number of bits different
-      from 8.) See below, for the numbering of bits within a byte.
-
-   1.6. Changes from previous versions
-
-      Version 3.1 was the first public release of this specification.
-      In version 3.2, some terminology was changed and the Adler-32
-      sample code was rewritten for clarity.  In version 3.3, the
-      support for a preset dictionary was introduced, and the
-      specification was converted to RFC style.
-
-2. Detailed specification
-
-   2.1. Overall conventions
-
-      In the diagrams below, a box like this:
-
-         +---+
-         |   | <-- the vertical bars might be missing
-         +---+

-
-RFC 1950       ZLIB Compressed Data Format Specification        May 1996
-
-
-      represents one byte; a box like this:
-
-         +==============+
-         |              |
-         +==============+
-
-      represents a variable number of bytes.
-
-      Bytes stored within a computer do not have a "bit order", since
-      they are always treated as a unit.  However, a byte considered as
-      an integer between 0 and 255 does have a most- and least-
-      significant bit, and since we write numbers with the most-
-      significant digit on the left, we also write bytes with the most-
-      significant bit on the left.  In the diagrams below, we number the
-      bits of a byte so that bit 0 is the least-significant bit, i.e.,
-      the bits are numbered:
-
-         +--------+
-         |76543210|
-         +--------+
-
-      Within a computer, a number may occupy multiple bytes.  All
-      multi-byte numbers in the format described here are stored with
-      the MOST-significant byte first (at the lower memory address).
-      For example, the decimal number 520 is stored as:
-
-             0     1
-         +--------+--------+
-         |00000010|00001000|
-         +--------+--------+
-          ^        ^
-          |        |
-          |        + less significant byte = 8
-          + more significant byte = 2 x 256
-
-   2.2. Data format
-
-      A zlib stream has the following structure:
-
-           0   1
-         +---+---+
-         |CMF|FLG|   (more-->)
-         +---+---+

-
-RFC 1950       ZLIB Compressed Data Format Specification        May 1996
-
-
-      (if FLG.FDICT set)
-
-           0   1   2   3
-         +---+---+---+---+
-         |     DICTID    |   (more-->)
-         +---+---+---+---+
-
-         +=====================+---+---+---+---+
-         |...compressed data...|    ADLER32    |
-         +=====================+---+---+---+---+
-
-      Any data which may appear after ADLER32 are not part of the zlib
-      stream.
-
-      CMF (Compression Method and flags)
-         This byte is divided into a 4-bit compression method and a 4-
-         bit information field depending on the compression method.
-
-            bits 0 to 3  CM     Compression method
-            bits 4 to 7  CINFO  Compression info
-
-      CM (Compression method)
-         This identifies the compression method used in the file. CM = 8
-         denotes the "deflate" compression method with a window size up
-         to 32K.  This is the method used by gzip and PNG (see
-         references [1] and [2] in Chapter 3, below, for the reference
-         documents).  CM = 15 is reserved.  It might be used in a future
-         version of this specification to indicate the presence of an
-         extra field before the compressed data.
-
-      CINFO (Compression info)
-         For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
-         size, minus eight (CINFO=7 indicates a 32K window size). Values
-         of CINFO above 7 are not allowed in this version of the
-         specification.  CINFO is not defined in this specification for
-         CM not equal to 8.
-
-      FLG (FLaGs)
-         This flag byte is divided as follows:
-
-            bits 0 to 4  FCHECK  (check bits for CMF and FLG)
-            bit  5       FDICT   (preset dictionary)
-            bits 6 to 7  FLEVEL  (compression level)
-
-         The FCHECK value must be such that CMF and FLG, when viewed as
-         a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
-         is a multiple of 31.

-
-
-      FDICT (Preset dictionary)
-         If FDICT is set, a DICT dictionary identifier is present
-         immediately after the FLG byte. The dictionary is a sequence of
-         bytes which are initially fed to the compressor without
-         producing any compressed output. DICT is the Adler-32 checksum
-         of this sequence of bytes (see the definition of ADLER32
-         below).  The decompressor can use this identifier to determine
-         which dictionary has been used by the compressor.
-
-      FLEVEL (Compression level)
-         These flags are available for use by specific compression
-         methods.  The "deflate" method (CM = 8) sets these flags as
-         follows:
-
-            0 - compressor used fastest algorithm
-            1 - compressor used fast algorithm
-            2 - compressor used default algorithm
-            3 - compressor used maximum compression, slowest algorithm
-
-         The information in FLEVEL is not needed for decompression; it
-         is there to indicate if recompression might be worthwhile.
-
-      compressed data
-         For compression method 8, the compressed data is stored in the
-         deflate compressed data format as described in the document
-         "DEFLATE Compressed Data Format Specification" by L. Peter
-         Deutsch. (See reference [3] in Chapter 3, below)
-
-         Other compressed data formats are not specified in this version
-         of the zlib specification.
-
-      ADLER32 (Adler-32 checksum)
-         This contains a checksum value of the uncompressed data
-         (excluding any dictionary data) computed according to Adler-32
-         algorithm. This algorithm is a 32-bit extension and improvement
-         of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
-         standard. See references [4] and [5] in Chapter 3, below)
-
-         Adler-32 is composed of two sums accumulated per byte: s1 is
-         the sum of all bytes, s2 is the sum of all s1 values. Both sums
-         are done modulo 65521. s1 is initialized to 1, s2 to zero.  The
-         Adler-32 checksum is stored as s2*65536 + s1 in most-
-         significant-byte first (network) order.

-
-
-   2.3. Compliance
-
-      A compliant compressor must produce streams with correct CMF, FLG
-      and ADLER32, but need not support preset dictionaries.  When the
-      zlib data format is used as part of another standard data format,
-      the compressor may use only preset dictionaries that are specified
-      by this other data format.  If this other format does not use the
-      preset dictionary feature, the compressor must not set the FDICT
-      flag.
-
-      A compliant decompressor must check CMF, FLG, and ADLER32, and
-      provide an error indication if any of these have incorrect values.
-      A compliant decompressor must give an error indication if CM is
-      not one of the values defined in this specification (only the
-      value 8 is permitted in this version), since another value could
-      indicate the presence of new features that would cause subsequent
-      data to be interpreted incorrectly.  A compliant decompressor must
-      give an error indication if FDICT is set and DICTID is not the
-      identifier of a known preset dictionary.  A decompressor may
-      ignore FLEVEL and still be compliant.  When the zlib data format
-      is being used as a part of another standard format, a compliant
-      decompressor must support all the preset dictionaries specified by
-      the other format. When the other format does not use the preset
-      dictionary feature, a compliant decompressor must reject any
-      stream in which the FDICT flag is set.

-8. Appendix: Rationale
-
-   8.1. Preset dictionaries
-
-      A preset dictionary is specially useful to compress short input
-      sequences. The compressor can take advantage of the dictionary
-      context to encode the input in a more compact manner. The
-      decompressor can be initialized with the appropriate context by
-      virtually decompressing a compressed version of the dictionary
-      without producing any output. However for certain compression
-      algorithms such as the deflate algorithm this operation can be
-      achieved without actually performing any decompression.
-
-      The compressor and the decompressor must use exactly the same
-      dictionary. The dictionary may be fixed or may be chosen among a
-      certain number of predefined dictionaries, according to the kind
-      of input data. The decompressor can determine which dictionary has
-      been chosen by the compressor by checking the dictionary
-      identifier. This document does not specify the contents of
-      predefined dictionaries, since the optimal dictionaries are
-      application specific. Standard data formats using this feature of
-      the zlib specification must precisely define the allowed
-      dictionaries.
-
-   8.2. The Adler-32 algorithm
-
-      The Adler-32 algorithm is much faster than the CRC32 algorithm yet
-      still provides an extremely low probability of undetected errors.
-
-      The modulo on unsigned long accumulators can be delayed for 5552
-      bytes, so the modulo operation time is negligible.  If the bytes
-      are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
-      and order sensitive, unlike the first sum, which is just a
-      checksum.  That 65521 is prime is important to avoid a possible
-      large class of two-byte errors that leave the check unchanged.
-      (The Fletcher checksum uses 255, which is not prime and which also
-      makes the Fletcher check insensitive to single byte changes 0 <->
-      255.)
-
-      The sum s1 is initialized to 1 instead of zero to make the length
-      of the sequence part of s2, so that the length does not have to be
-      checked separately. (Any sequence of zeroes has a Fletcher
-      checksum of zero.)

-9. Appendix: Sample code
-
-   The following C code computes the Adler-32 checksum of a data buffer.
-   It is written for clarity, not for speed.  The sample code is in the
-   ANSI C programming language. Non C users may find it easier to read
-   with these hints:
-
-      &      Bitwise AND operator.
-      >>     Bitwise right shift operator. When applied to an
-             unsigned quantity, as here, right shift inserts zero bit(s)
-             at the left.

-1. Introduction
-
-   1.1. Purpose
-
-      The purpose of this specification is to define a lossless
-      compressed data format that:
-          * Is independent of CPU type, operating system, file system,
-            and character set, and hence can be used for interchange;
-          * Can be produced or consumed, even for an arbitrarily long
-            sequentially presented input data stream, using only an a
-            priori bounded amount of intermediate storage, and hence
-            can be used in data communications or similar structures
-            such as Unix filters;
-          * Compresses data with efficiency comparable to the best
-            currently available general-purpose compression methods,
-            and in particular considerably better than the "compress"
-            program;
-          * Can be implemented readily in a manner not covered by
-            patents, and hence can be practiced freely;

-RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
-
-
-          * Is compatible with the file format produced by the current
-            widely used gzip utility, in that conforming decompressors
-            will be able to read data produced by the existing gzip
-            compressor.
-
-      The data format defined by this specification does not attempt to:
-
-          * Allow random access to compressed data;
-          * Compress specialized data (e.g., raster graphics) as well
-            as the best currently available specialized algorithms.
-
-      A simple counting argument shows that no lossless compression
-      algorithm can compress every possible input data set.  For the
-      format defined here, the worst case expansion is 5 bytes per 32K-
-      byte block, i.e., a size increase of 0.015% for large data sets.
-      English text usually compresses by a factor of 2.5 to 3;
-      executable files usually compress somewhat less; graphical data
-      such as raster images may compress much more.
-
-   1.2. Intended audience
-
-      This specification is intended for use by implementors of software
-      to compress data into "deflate" format and/or decompress data from
-      "deflate" format.
-
-      The text of the specification assumes a basic background in
-      programming at the level of bits and other primitive data
-      representations.  Familiarity with the technique of Huffman coding
-      is helpful but not required.
-
-   1.3. Scope
-
-      The specification specifies a method for representing a sequence
-      of bytes as a (usually shorter) sequence of bits, and a method for
-      packing the latter bit sequence into bytes.
-
-   1.4. Compliance
-
-      Unless otherwise indicated below, a compliant decompressor must be
-      able to accept and decompress any data set that conforms to all
-      the specifications presented here; a compliant compressor must
-      produce data sets that conform to all the specifications presented
-      here.
-
-   1.5.  Definitions of terms and conventions used
-
-      Byte: 8 bits stored or transmitted as a unit (same as an octet).
-      For this specification, a byte is exactly 8 bits, even on machines
-

-
-      which store a character on a number of bits different from eight.
-      See below, for the numbering of bits within a byte.
-
-      String: a sequence of arbitrary bytes.
-
-   1.6. Changes from previous versions
-
-      There have been no technical changes to the deflate format since
-      version 1.1 of this specification.  In version 1.2, some
-      terminology was changed.  Version 1.3 is a conversion of the
-      specification to RFC style.
-
-2. Compressed representation overview
-
-   A compressed data set consists of a series of blocks, corresponding
-   to successive blocks of input data.  The block sizes are arbitrary,
-   except that non-compressible blocks are limited to 65,535 bytes.
-
-   Each block is compressed using a combination of the LZ77 algorithm
-   and Huffman coding. The Huffman trees for each block are independent
-   of those for previous or subsequent blocks; the LZ77 algorithm may
-   use a reference to a duplicated string occurring in a previous block,
-   up to 32K input bytes before.
-
-   Each block consists of two parts: a pair of Huffman code trees that
-   describe the representation of the compressed data part, and a
-   compressed data part.  (The Huffman trees themselves are compressed
-   using Huffman encoding.)  The compressed data consists of a series of
-   elements of two types: literal bytes (of strings that have not been
-   detected as duplicated within the previous 32K input bytes), and
-   pointers to duplicated strings, where a pointer is represented as a
-   pair <length, backward distance>.  The representation used in the
-   "deflate" format limits distances to 32K bytes and lengths to 258
-   bytes, but does not limit the size of a block, except for
-   uncompressible blocks, which are limited as noted above.
-
-   Each type of value (literals, distances, and lengths) in the
-   compressed data is represented using a Huffman code, using one code
-   tree for literals and lengths and a separate code tree for distances.
-   The code trees for each block appear in a compact form just before
-   the compressed data for that block.

-3. Detailed specification
-
-   3.1. Overall conventions In the diagrams below, a box like this:
-
-         +---+
-         |   | <-- the vertical bars might be missing
-         +---+
-
-      represents one byte; a box like this:
-
-         +==============+
-         |              |
-         +==============+
-
-      represents a variable number of bytes.
-
-      Bytes stored within a computer do not have a "bit order", since
-      they are always treated as a unit.  However, a byte considered as
-      an integer between 0 and 255 does have a most- and least-
-      significant bit, and since we write numbers with the most-
-      significant digit on the left, we also write bytes with the most-
-      significant bit on the left.  In the diagrams below, we number the
-      bits of a byte so that bit 0 is the least-significant bit, i.e.,
-      the bits are numbered:
-
-         +--------+
-         |76543210|
-         +--------+
-
-      Within a computer, a number may occupy multiple bytes.  All
-      multi-byte numbers in the format described here are stored with
-      the least-significant byte first (at the lower memory address).
-      For example, the decimal number 520 is stored as:
-
-             0        1
-         +--------+--------+
-         |00001000|00000010|
-         +--------+--------+
-          ^        ^
-          |        |
-          |        + more significant byte = 2 x 256
-          + less significant byte = 8
-
-      3.1.1. Packing into bytes
-
-         This document does not address the issue of the order in which
-         bits of a byte are transmitted on a bit-sequential medium,
-         since the final data format described here is byte- rather than
-
-
-
-Deutsch                      Informational                      [Page 5]
-
-RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
-
-
-         bit-oriented.  However, we describe the compressed block format
-         in below, as a sequence of data elements of various bit
-         lengths, not a sequence of bytes.  We must therefore specify
-         how to pack these data elements into bytes to form the final
-         compressed byte sequence:
-
-             * Data elements are packed into bytes in order of
-               increasing bit number within the byte, i.e., starting
-               with the least-significant bit of the byte.
-             * Data elements other than Huffman codes are packed
-               starting with the least-significant bit of the data
-               element.
-             * Huffman codes are packed starting with the most-
-               significant bit of the code.
-
-         In other words, if one were to print out the compressed data as
-         a sequence of bytes, starting with the first byte at the
-         *right* margin and proceeding to the *left*, with the most-
-         significant bit of each byte on the left as usual, one would be
-         able to parse the result from right to left, with fixed-width
-         elements in the correct MSB-to-LSB order and Huffman codes in
-         bit-reversed order (i.e., with the first bit of the code in the
-         relative LSB position).
-
-   3.2. Compressed block format
-
-      3.2.1. Synopsis of prefix and Huffman coding
-
-         Prefix coding represents symbols from an a priori known
-         alphabet by bit sequences (codes), one code for each symbol, in
-         a manner such that different symbols may be represented by bit
-         sequences of different lengths, but a parser can always parse
-         an encoded string unambiguously symbol-by-symbol.
-
-         We define a prefix code in terms of a binary tree in which the
-         two edges descending from each non-leaf node are labeled 0 and
-         1 and in which the leaf nodes correspond one-for-one with (are
-         labeled with) the symbols of the alphabet; then the code for a
-         symbol is the sequence of 0's and 1's on the edges leading from
-         the root to the leaf labeled with that symbol.  For example:

-                          /\              Symbol    Code
-                         0  1             ------    ----
-                        /    \                A      00
-                       /\     B               B       1
-                      0  1                    C     011
-                     /    \                   D     010
-                    A     /\
-                         0  1
-                        /    \
-                       D      C
-
-         A parser can decode the next symbol from an encoded input
-         stream by walking down the tree from the root, at each step
-         choosing the edge corresponding to the next input bit.
-
-         Given an alphabet with known symbol frequencies, the Huffman
-         algorithm allows the construction of an optimal prefix code
-         (one which represents strings with those symbol frequencies
-         using the fewest bits of any possible prefix codes for that
-         alphabet).  Such a code is called a Huffman code.  (See
-         reference [1] in Chapter 5, references for additional
-         information on Huffman codes.)
-
-         Note that in the "deflate" format, the Huffman codes for the
-         various alphabets must not exceed certain maximum code lengths.
-         This constraint complicates the algorithm for computing code
-         lengths from symbol frequencies.  Again, see Chapter 5,
-         references for details.
-
-      3.2.2. Use of Huffman coding in the "deflate" format
-
-         The Huffman codes used for each alphabet in the "deflate"
-         format have two additional rules:
-
-             * All codes of a given bit length have lexicographically
-               consecutive values, in the same order as the symbols
-               they represent;
-
-             * Shorter codes lexicographically precede longer codes.
-
-

-
-RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
-
-
-         We could recode the example above to follow this rule as
-         follows, assuming that the order of the alphabet is ABCD:
-
-            Symbol  Code
-            ------  ----
-            A       10
-            B       0
-            C       110
-            D       111
-
-         I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
-         lexicographically consecutive.
-
-         Given this rule, we can define the Huffman code for an alphabet
-         just by giving the bit lengths of the codes for each symbol of
-         the alphabet in order; this is sufficient to determine the
-         actual codes.  In our example, the code is completely defined
-         by the sequence of bit lengths (2, 1, 3, 3).  The following
-         algorithm generates the codes as integers, intended to be read
-         from most- to least-significant bit.  The code lengths are
-         initially in tree[I].Len; the codes are produced in
-         tree[I].Code.
-
-         1)  Count the number of codes for each code length.  Let
-             bl_count[N] be the number of codes of length N, N >= 1.
-
-         2)  Find the numerical value of the smallest code for each
-             code length:
-
-                code = 0;
-                bl_count[0] = 0;
-                for (bits = 1; bits <= MAX_BITS; bits++) {
-                    code = (code + bl_count[bits-1]) << 1;
-                    next_code[bits] = code;
-                }
-
-         3)  Assign numerical values to all codes, using consecutive
-             values for all codes of the same length with the base
-             values determined at step 2. Codes that are never used
-             (which have a bit length of zero) must not be assigned a
-             value.

-
-         Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3,
-         3, 2, 4, 4).  After step 1, we have:

-      3.2.3. Details of block format
-
-         Each block of compressed data begins with 3 header bits
-         containing the following data:
-
-            first bit       BFINAL
-            next 2 bits     BTYPE
-
-         Note that the header bits do not necessarily begin on a byte
-         boundary, since a block does not necessarily occupy an integral
-         number of bytes.
-
-

-
-RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
-
-
-         BFINAL is set if and only if this is the last block of the data
-         set.
-
-         BTYPE specifies how the data are compressed, as follows:
-
-            00 - no compression
-            01 - compressed with fixed Huffman codes
-            10 - compressed with dynamic Huffman codes
-            11 - reserved (error)
-
-         The only difference between the two compressed cases is how the
-         Huffman codes for the literal/length and distance alphabets are
-         defined.
-
-         In all cases, the decoding algorithm for the actual data is as
-         follows:
-
-            do
-               read block header from input stream.
-               if stored with no compression
-                  skip any remaining bits in current partially
-                     processed byte
-                  read LEN and NLEN (see next section)
-                  copy LEN bytes of data to output
-               otherwise
-                  if compressed with dynamic Huffman codes
-                     read representation of code trees (see
-                        subsection below)
-                  loop (until end of block code recognized)
-                     decode literal/length value from input stream
-                     if value < 256
-                        copy value (literal byte) to output stream
-                     otherwise
-                        if value = end of block (256)
-                           break from loop
-                        otherwise (value = 257..285)
-                           decode distance from input stream
-
-                           move backwards distance bytes in the output
-                           stream, and copy length bytes from this
-                           position to the output stream.
-                  end loop
-            while not last block
-
-         Note that a duplicated string reference may refer to a string
-         in a previous block; i.e., the backward distance may cross one
-         or more block boundaries.  However a distance cannot refer past
-         the beginning of the output stream.  (An application using a

-
-
-         preset dictionary might discard part of the output stream; a
-         distance can refer to that part of the output stream anyway)
-         Note also that the referenced string may overlap the current
-         position; for example, if the last 2 bytes decoded have values
-         X and Y, a string reference with <length = 5, distance = 2>
-         adds X,Y,X,Y,X to the output stream.
-
-         We now specify each compression method in turn.
-
-      3.2.4. Non-compressed blocks (BTYPE=00)
-
-         Any bits of input up to the next byte boundary are ignored.
-         The rest of the block consists of the following information:
-
-              0   1   2   3   4...
-            +---+---+---+---+================================+
-            |  LEN  | NLEN  |... LEN bytes of literal data...|
-            +---+---+---+---+================================+
-
-         LEN is the number of data bytes in the block.  NLEN is the
-         one's complement of LEN.
-
-      3.2.5. Compressed blocks (length and distance codes)
-
-         As noted above, encoded data blocks in the "deflate" format
-         consist of sequences of symbols drawn from three conceptually
-         distinct alphabets: either literal bytes, from the alphabet of
-         byte values (0..255), or <length, backward distance> pairs,
-         where the length is drawn from (3..258) and the distance is
-         drawn from (1..32,768).  In fact, the literal and length
-         alphabets are merged into a single alphabet (0..285), where
-         values 0..255 represent literal bytes, the value 256 indicates
-         end-of-block, and values 257..285 represent length codes
-         (possibly in conjunction with extra bits following the symbol
-         code) as follows:

-
-         The code lengths are sufficient to generate the actual codes,
-         as described above; we show the codes in the table for added
-         clarity.  Literal/length values 286-287 will never actually
-         occur in the compressed data, but participate in the code
-         construction.
-
-         Distance codes 0-31 are represented by (fixed-length) 5-bit
-         codes, with possible additional bits as shown in the table
-         shown in Paragraph 3.2.5, above.  Note that distance codes 30-
-         31 will never actually occur in the compressed data.
-
-      3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
-
-         The Huffman codes for the two alphabets appear in the block
-         immediately after the header bits and before the actual
-         compressed data, first the literal/length code and then the
-         distance code.  Each code is defined by a sequence of code
-         lengths, as discussed in Paragraph 3.2.2, above.  For even
-         greater compactness, the code length sequences themselves are
-         compressed using a Huffman code.  The alphabet for code lengths
-         is as follows:
-
-               0 - 15: Represent code lengths of 0 - 15
-                   16: Copy the previous code length 3 - 6 times.
-                       The next 2 bits indicate repeat length
-                             (0 = 3, ... , 3 = 6)
-                          Example:  Codes 8, 16 (+2 bits 11),
-                                    16 (+2 bits 10) will expand to
-                                    12 code lengths of 8 (1 + 6 + 5)
-                   17: Repeat a code length of 0 for 3 - 10 times.
-                       (3 bits of length)
-                   18: Repeat a code length of 0 for 11 - 138 times
-                       (7 bits of length)
-
-         A code length of 0 indicates that the corresponding symbol in
-         the literal/length or distance alphabet will not occur in the
-         block, and should not participate in the Huffman code
-         construction algorithm given earlier.  If only one distance
-         code is used, it is encoded using one bit, not zero bits; in
-         this case there is a single code length of one, with one unused
-         code.  One distance code of zero bits means that there are no
-         distance codes used at all (the data is all literals).
-
-         We can now define the format of the block:
-
-               5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
-               5 Bits: HDIST, # of Distance codes - 1        (1 - 32)
-               4 Bits: HCLEN, # of Code Length codes - 4     (4 - 19)
-

-
-
-               (HCLEN + 4) x 3 bits: code lengths for the code length
-                  alphabet given just above, in the order: 16, 17, 18,
-                  0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
-
-                  These code lengths are interpreted as 3-bit integers
-                  (0-7); as above, a code length of 0 means the
-                  corresponding symbol (literal/length or distance code
-                  length) is not used.
-
-               HLIT + 257 code lengths for the literal/length alphabet,
-                  encoded using the code length Huffman code
-
-               HDIST + 1 code lengths for the distance alphabet,
-                  encoded using the code length Huffman code
-
-               The actual compressed data of the block,
-                  encoded using the literal/length and distance Huffman
-                  codes
-
-               The literal/length symbol 256 (end of data),
-                  encoded using the literal/length Huffman code
-
-         The code length repeat codes can cross from HLIT + 257 to the
-         HDIST + 1 code lengths.  In other words, all code lengths form
-         a single sequence of HLIT + HDIST + 258 values.
-
-   3.3. Compliance
-
-      A compressor may limit further the ranges of values specified in
-      the previous section and still be compliant; for example, it may
-      limit the range of backward pointers to some value smaller than
-      32K.  Similarly, a compressor may limit the size of blocks so that
-      a compressible block fits in memory.
-
-      A compliant decompressor must accept the full range of possible
-      values defined in the previous section, and must accept blocks of
-      arbitrary size.

-4. Compression algorithm details
-
-   While it is the intent of this document to define the "deflate"
-   compressed data format without reference to any particular
-   compression algorithm, the format is related to the compressed
-   formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
-   since many variations of LZ77 are patented, it is strongly
-   recommended that the implementor of a compressor follow the general
-   algorithm presented here, which is known not to be patented per se.
-   The material in this section is not part of the definition of the

-   The compressor terminates a block when it determines that starting a
-   new block with fresh trees would be useful, or when the block size
-   fills up the compressor's block buffer.
-
-   The compressor uses a chained hash table to find duplicated strings,
-   using a hash function that operates on 3-byte sequences.  At any
-   given point during compression, let XYZ be the next 3 input bytes to
-   be examined (not necessarily all different, of course).  First, the
-   compressor examines the hash chain for XYZ.  If the chain is empty,
-   the compressor simply writes out X as a literal byte and advances one
-   byte in the input.  If the hash chain is not empty, indicating that
-   the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
-   same hash function value) has occurred recently, the compressor
-   compares all strings on the XYZ hash chain with the actual input data
-   sequence starting at the current point, and selects the longest
-   match.
-
-   The compressor searches the hash chains starting with the most recent
-   strings, to favor small distances and thus take advantage of the
-   Huffman encoding.  The hash chains are singly linked. There are no
-   deletions from the hash chains; the algorithm simply discards matches
-   that are too old.  To avoid a worst-case situation, very long hash
-   chains are arbitrarily truncated at a certain length, determined by a
-   run-time parameter.
-
-   To improve overall compression, the compressor optionally defers the
-   selection of matches ("lazy matching"): after a match of length N has
-   been found, the compressor searches for a longer match starting at
-   the next input byte.  If it finds a longer match, it truncates the
-   previous match to a length of one (thus producing a single literal
-   byte) and then emits the longer match.  Otherwise, it emits the
-   original match, and, as described above, advances N bytes before
-   continuing.
-
-   Run-time parameters also control this "lazy match" procedure.  If
-   compression ratio is most important, the compressor attempts a
-   complete second search regardless of the length of the first match.
-   In the normal case, if the current match is "long enough", the
-   compressor reduces the search for a longer match, thus speeding up
-   the process.  If speed is most important, the compressor inserts new
-   strings in the hash table only when no match was found, or when the
-   match is not "too long".  This degrades the compression ratio but
-   saves time since there are both fewer insertions and fewer searches.

-Abstract
-
-   This specification defines a lossless compressed data format that is
-   compatible with the widely used GZIP utility.  The format includes a
-   cyclic redundancy check value for detecting data corruption.  The
-   format presently uses the DEFLATE method of compression but can be
-   easily extended to use other compression methods.  The format can be
-   implemented readily in a manner not covered by patents.

-1. Introduction
-
-   1.1. Purpose
-
-      The purpose of this specification is to define a lossless
-      compressed data format that:
-
-          * Is independent of CPU type, operating system, file system,
-            and character set, and hence can be used for interchange;
-          * Can compress or decompress a data stream (as opposed to a
-            randomly accessible file) to produce another data stream,
-            using only an a priori bounded amount of intermediate
-            storage, and hence can be used in data communications or
-            similar structures such as Unix filters;
-          * Compresses data with efficiency comparable to the best
-            currently available general-purpose compression methods,
-            and in particular considerably better than the "compress"
-            program;
-          * Can be implemented readily in a manner not covered by
-            patents, and hence can be practiced freely;
-          * Is compatible with the file format produced by the current
-            widely used gzip utility, in that conforming decompressors
-            will be able to read data produced by the existing gzip
-            compressor.

-RFC 1952             GZIP File Format Specification             May 1996
-
-
-      The data format defined by this specification does not attempt to:
-
-          * Provide random access to compressed data;
-          * Compress specialized data (e.g., raster graphics) as well as
-            the best currently available specialized algorithms.
-
-   1.2. Intended audience
-
-      This specification is intended for use by implementors of software
-      to compress data into gzip format and/or decompress data from gzip
-      format.
-
-      The text of the specification assumes a basic background in
-      programming at the level of bits and other primitive data
-      representations.
-
-   1.3. Scope
-
-      The specification specifies a compression method and a file format
-      (the latter assuming only that a file can store a sequence of
-      arbitrary bytes).  It does not specify any particular interface to
-      a file system or anything about character sets or encodings
-      (except for file names and comments, which are optional).
-
-   1.4. Compliance
-
-      Unless otherwise indicated below, a compliant decompressor must be
-      able to accept and decompress any file that conforms to all the
-      specifications presented here; a compliant compressor must produce
-      files that conform to all the specifications presented here.  The
-      material in the appendices is not part of the specification per se
-      and is not relevant to compliance.
-
-   1.5. Definitions of terms and conventions used
-
-      byte: 8 bits stored or transmitted as a unit (same as an octet).
-      (For this specification, a byte is exactly 8 bits, even on
-      machines which store a character on a number of bits different
-      from 8.)  See below for the numbering of bits within a byte.
-
-   1.6. Changes from previous versions
-
-      There have been no technical changes to the gzip format since
-      version 4.1 of this specification.  In version 4.2, some
-      terminology was changed, and the sample CRC code was rewritten for
-      clarity and to eliminate the requirement for the caller to do pre-
-      and post-conditioning.  Version 4.3 is a conversion of the
-      specification to RFC style.

-2. Detailed specification
-
-   2.1. Overall conventions
-
-      In the diagrams below, a box like this:
-
-         +---+
-         |   | <-- the vertical bars might be missing
-         +---+
-
-      represents one byte; a box like this:
-
-         +==============+
-         |              |
-         +==============+
-
-      represents a variable number of bytes.
-
-      Bytes stored within a computer do not have a "bit order", since
-      they are always treated as a unit.  However, a byte considered as
-      an integer between 0 and 255 does have a most- and least-
-      significant bit, and since we write numbers with the most-
-      significant digit on the left, we also write bytes with the most-
-      significant bit on the left.  In the diagrams below, we number the
-      bits of a byte so that bit 0 is the least-significant bit, i.e.,
-      the bits are numbered:
-
-         +--------+
-         |76543210|
-         +--------+
-
-      This document does not address the issue of the order in which
-      bits of a byte are transmitted on a bit-sequential medium, since
-      the data format described here is byte- rather than bit-oriented.
-
-      Within a computer, a number may occupy multiple bytes.  All
-      multi-byte numbers in the format described here are stored with
-      the least-significant byte first (at the lower memory address).
-      For example, the decimal number 520 is stored as:
-
-             0        1
-         +--------+--------+
-         |00001000|00000010|
-         +--------+--------+
-          ^        ^
-          |        |
-          |        + more significant byte = 2 x 256
-          + less significant byte = 8

-
-
-   2.2. File format
-
-      A gzip file consists of a series of "members" (compressed data
-      sets).  The format of each member is specified in the following
-      section.  The members simply appear one after another in the file,
-      with no additional information before, between, or after them.
-
-   2.3. Member format
-
-      Each member has the following structure:
-
-         +---+---+---+---+---+---+---+---+---+---+
-         |ID1|ID2|CM |FLG|     MTIME     |XFL|OS | (more-->)
-         +---+---+---+---+---+---+---+---+---+---+
-
-      (if FLG.FEXTRA set)
-
-         +---+---+=================================+
-         | XLEN  |...XLEN bytes of "extra field"...| (more-->)
-         +---+---+=================================+
-
-      (if FLG.FNAME set)
-
-         +=========================================+
-         |...original file name, zero-terminated...| (more-->)
-         +=========================================+
-
-      (if FLG.FCOMMENT set)
-
-         +===================================+
-         |...file comment, zero-terminated...| (more-->)
-         +===================================+
-
-      (if FLG.FHCRC set)

-
-         ID1 (IDentification 1)
-         ID2 (IDentification 2)
-            These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
-            (0x8b, \213), to identify the file as being in gzip format.
-
-         CM (Compression Method)
-            This identifies the compression method used in the file.  CM
-            = 0-7 are reserved.  CM = 8 denotes the "deflate"
-            compression method, which is the one customarily used by
-            gzip and which is documented elsewhere.
-
-         FLG (FLaGs)
-            This flag byte is divided into individual bits as follows:
-
-               bit 0   FTEXT
-               bit 1   FHCRC
-               bit 2   FEXTRA
-               bit 3   FNAME
-               bit 4   FCOMMENT
-               bit 5   reserved
-               bit 6   reserved
-               bit 7   reserved
-
-            If FTEXT is set, the file is probably ASCII text.  This is
-            an optional indication, which the compressor may set by
-            checking a small amount of the input data to see whether any
-            non-ASCII characters are present.  In case of doubt, FTEXT
-            is cleared, indicating binary data. For systems which have
-            different file formats for ascii text and binary data, the
-            decompressor can use FTEXT to choose the appropriate format.
-            We deliberately do not specify the algorithm used to set
-            this bit, since a compressor always has the option of
-            leaving it cleared and a decompressor always has the option
-            of ignoring it and letting some other program handle issues
-            of data conversion.
-
-            If FHCRC is set, a CRC16 for the gzip header is present,
-            immediately before the compressed data. The CRC16 consists
-            of the two least significant bytes of the CRC32 for all
-            bytes of the gzip header up to and not including the CRC16.
-            [The FHCRC bit was never set by versions of gzip up to
-            1.2.4, even though it was documented with a different
-            meaning in gzip 1.2.4.]
-
-            If FEXTRA is set, optional extra fields are present, as
-            described in a following section.

-
-
-            If FNAME is set, an original file name is present,
-            terminated by a zero byte.  The name must consist of ISO
-            8859-1 (LATIN-1) characters; on operating systems using
-            EBCDIC or any other character set for file names, the name
-            must be translated to the ISO LATIN-1 character set.  This
-            is the original name of the file being compressed, with any
-            directory components removed, and, if the file being
-            compressed is on a file system with case insensitive names,
-            forced to lower case. There is no original file name if the
-            data was compressed from a source other than a named file;
-            for example, if the source was stdin on a Unix system, there
-            is no file name.
-
-            If FCOMMENT is set, a zero-terminated file comment is
-            present.  This comment is not interpreted; it is only
-            intended for human consumption.  The comment must consist of
-            ISO 8859-1 (LATIN-1) characters.  Line breaks should be
-            denoted by a single line feed character (10 decimal).
-
-            Reserved FLG bits must be zero.
-
-         MTIME (Modification TIME)
-            This gives the most recent modification time of the original
-            file being compressed.  The time is in Unix format, i.e.,
-            seconds since 00:00:00 GMT, Jan.  1, 1970.  (Note that this
-            may cause problems for MS-DOS and other systems that use

-         If the FLG.FEXTRA bit is set, an "extra field" is present in

-      2.3.1.2. Compliance
-
-         A compliant compressor must produce files with correct ID1,
-         ID2, CM, CRC32, and ISIZE, but may set all the other fields in
-         the fixed-length part of the header to default values (255 for
-         OS, 0 for all others).  The compressor must set all reserved
-         bits to zero.
-
-         A compliant decompressor must check ID1, ID2, and CM, and
-         provide an error indication if any of these have incorrect
-         values.  It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
-         at least so it can skip over the optional fields if they are
-         present.  It need not examine any other part of the header or
-         trailer; in particular, a decompressor may ignore FTEXT and OS
-         and always produce binary output, and still be compliant.  A
-         compliant decompressor must give an error indication if any
-         reserved bit is non-zero, since such a bit could indicate the
-         presence of a new field that would cause subsequent data to be
-         interpreted incorrectly.

-   severe effects and be difficult to correct.  Uncompressed text, on
-   the other hand, will probably still be readable despite the presence
-   of some corrupted bytes.
-
-   It is recommended that systems using this data format provide some
-   means of validating the integrity of the compressed data, such as by
-   setting and checking the CRC-32 check value.

-7. Appendix: Jean-Loup Gailly's gzip utility
-
-   The most widely used implementation of gzip compression, and the
-   original documentation on which this specification is based, were
-   created by Jean-Loup Gailly <gzip@prep.ai.mit.edu>.  Since this
-   implementation is a de facto standard, we mention some more of its
-   features here.  Again, the material in this section is not part of
-   the specification per se, and implementations need not follow it to
-   be compliant.
-
-   When compressing or decompressing a file, gzip preserves the
-   protection, ownership, and modification time attributes on the local
-   file system, since there is no provision for representing protection
-   attributes in the gzip file format itself.  Since the file format
-   includes a modification time, the gzip decompressor provides a
-   command line switch that assigns the modification time from the file,
-   rather than the local modification time of the compressed input, to
-   the decompressed output.
-
-8. Appendix: Sample CRC Code
-
-   The following sample code represents a practical implementation of
-   the CRC (Cyclic Redundancy Check). (See also ISO 3309 and ITU-T V.42
-   for a formal specification.)
-
-   The sample code is in the ANSI C programming language. Non C users
-   may find it easier to read with these hints:
-
-      &      Bitwise AND operator.
-      ^      Bitwise exclusive-OR operator.
-      >>     Bitwise right shift operator. When applied to an
-             unsigned quantity, as here, right shift inserts zero
-             bit(s) at the left.
-      !      Logical NOT operator.
-      ++     "n++" increments the variable n.
-      0xNNN  0x introduces a hexadecimal (base 16) constant.
-             Suffix L indicates a long value (at least 32 bits).
-
-      /* Table of CRCs of all 8-bit messages. */
-      unsigned long crc_table[256];
-
-      /* Flag: has the table been computed? Initially false. */

-A Fast Method for Identifying Plain Text Files
-==============================================
-
-
-Introduction
------------
-
-Given a file coming from an unknown source, it is sometimes desirable
-to find out whether the format of that file is plain text.  Although
-this may appear like a simple task, a fully accurate detection of the
-file type requires heavy-duty semantic analysis on the file contents.
-It is, however, possible to obtain satisfactory results by employing
-various heuristics.
-
-Previous versions of PKZip and other zip-compatible compression tools
-were using a crude detection scheme: if more than 80% (4/5) of the bytes
-found in a certain buffer are within the range [7..127], the file is
-labeled as plain text, otherwise it is labeled as binary.  A prominent
-limitation of this scheme is the restriction to Latin-based alphabets.
-Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
-the bytes within the range [128..255], and texts using these alphabets
-are most often misidentified by this scheme; in other words, the rate
-of false negatives is sometimes too high, which means that the recall
-is low.  Another weakness of this scheme is a reduced precision, due to
-the false positives that may occur when binary files containing large
-amounts of textual characters are misidentified as plain text.
-
-In this article we propose a new, simple detection scheme that features
-a much increased precision and a near-100% recall.  This scheme is
-designed to work on ASCII, Unicode and other ASCII-derived alphabets,
-and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
-and variable-sized encodings (ISO-2022, UTF-8, etc.).  Wider encodings
-(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
-
-
-The Algorithm
-------------
-
-The algorithm works by dividing the set of bytecodes [0..255] into three
-categories:
- The white list of textual bytecodes:
-  9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
- The gray list of tolerated bytecodes:
-  7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
- The black list of undesired, non-textual bytecodes:
-  0 (NUL) to 6, 14 to 31.
-
-If a file contains at least one byte that belongs to the white list and
-no byte that belongs to the black list, then the file is categorized as
-plain text; otherwise, it is categorized as binary.  (The boundary case,
-when the file is empty, automatically falls into the latter category.)
-
-
-Rationale
---------
-
-The idea behind this algorithm relies on two observations.
-
-The first observation is that, although the full range of 7-bit codes
-[0..127] is properly specified by the ASCII standard, most control
-characters in the range [0..31] are not used in practice.  The only
-widely-used, almost universally-portable control codes are 9 (TAB),
-10 (LF) and 13 (CR).  There are a few more control codes that are
-recognized on a reduced range of platforms and text viewers/editors:
-7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
-codes are rarely (if ever) used alone, without being accompanied by
-some printable text.  Even the newer, portable text formats such as
-XML avoid using control characters outside the list mentioned here.
-
-The second observation is that most of the binary files tend to contain
-control characters, especially 0 (NUL).  Even though the older text
-detection schemes observe the presence of non-ASCII codes from the range
-[128..255], the precision rarely has to suffer if this upper range is
-labeled as textual, because the files that are genuinely binary tend to
-contain both control characters and codes from the upper range.  On the
-other hand, the upper range needs to be labeled as textual, because it
-is used by virtually all ASCII extensions.  In particular, this range is
-used for encoding non-Latin scripts.
-
-Since there is no counting involved, other than simply observing the
-presence or the absence of some byte values, the algorithm produces
-consistent results, regardless what alphabet encoding is being used.
-(If counting were involved, it could be possible to obtain different
-results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
-
-There is an extra category of plain text files that are "polluted" with
-one or more black-listed codes, either by mistake or by peculiar design
-considerations.  In such cases, a scheme that tolerates a small fraction
-of black-listed codes would provide an increased recall (i.e. more true
-positives).  This, however, incurs a reduced precision overall, since
-false positives are more likely to appear in binary files that contain
-large chunks of textual data.  Furthermore, "polluted" plain text should
-be regarded as binary by general-purpose text detection schemes, because
-general-purpose text processing algorithms might not be applicable.
-Under this premise, it is safe to say that our detection method provides
-a near-100% recall.
-
-Experiments have been run on many files coming from various platforms
-and applications.  We tried plain text files, system logs, source code,
-formatted office documents, compiled object code, etc.  The results
-confirm the optimistic assumptions about the capabilities of this
-algorithm.

-\fBtcl_precision\fR significant digits; the result may be shorter if
-the shorter result represents the original number exactly. If no
-result of at most \fBtcl_precision\fR digits is an exact representation
-of the original number, the one that is closest to the original
-number is chosen.
-If the original number lies precisely between two equally accurate
-decimal representations, then the one with an even value for the least
-significant digit is chosen; for instance, if \fBtcl_precision\fR is 3, then
-0.3125 will convert to 0.312, not 0.313, while 0.6875 will convert to
-0.688, not 0.687. Any string of trailing zeroes that remains is trimmed.

-a \fBtcl_precision\fR value of 17 digits is
-.QW perfect
-for IEEE floating-point in that it allows
-double-precision values to be converted to strings and back to
-binary with no loss of information. For this reason, you will often
-see it as a value in legacy code that must run on Tcl versions before
-8.5. It is no longer recommended; as noted above, a zero value is the
