-1. Introduction
----------------
-Tcl provides a powerful platform for creating integration applications that
-tie together diverse applications, protocols, devices, and frameworks.
-When paired with the Tk toolkit, Tcl provides the fastest and most powerful
-way to create GUI applications that run on PCs, Unix, and Mac OS X.
-Tcl can also be used for a variety of web-related tasks and for creating
-powerful command languages for applications.
-
-Tcl is maintained, enhanced, and distributed freely by the Tcl community.
-Source code development and tracking of bug reports and feature requests
-takes place at:
-
-	http://core.tcl.tk/
-
-Tcl/Tk release and mailing list services are hosted by SourceForge:
-
-	http://sourceforge.net/projects/tcl/
-
-with the Tcl Developer Xchange hosted at:
-
-	http://www.tcl.tk/
-
-Tcl is a freely available open source package.  You can do virtually
-anything you like with it, such as modifying it, redistributing it,
-and selling it either in whole or in part.  See the file
-"license.terms" for complete information.
-
-2. Documentation
-----------------
-
-Extensive documentation is available at our website.
-The home page for this release, including new features, is
-	http://www.tcl.tk/software/tcltk/8.7.html
-
-Detailed release notes can be found at the file distributions page
-by clicking on the relevant version.
-	http://sourceforge.net/projects/tcl/files/Tcl/
-
-Information about Tcl itself can be found at
-	http://www.tcl.tk/about/
-
-There have been many Tcl books on the market.  Many are mentioned in the Wiki:
-	http://wiki.tcl.tk/_/ref?N=25206
-
-To view the complete set of reference manual entries for Tcl 8.7 online,
-visit the URL:
-	http://www.tcl.tk/man/tcl8.7/
-
-2a. Unix Documentation
-----------------------
-
-The "doc" subdirectory in this release contains a complete set of
-reference manual entries for Tcl.  Files with extension ".1" are for
-programs (for example, tclsh.1); files with extension ".3" are for C
-library procedures; and files with extension ".n" describe Tcl
-commands.  The file "doc/Tcl.n" gives a quick summary of the Tcl
-language syntax.  To print any of the man pages on Unix, cd to the
-"doc" directory and invoke your favorite variant of troff using the
-normal -man macros, for example
-
-		ditroff -man Tcl.n
-
-to print Tcl.n.  If Tcl has been installed correctly and your "man" program
-supports it, you should be able to access the Tcl manual entries using the
-normal "man" mechanisms, such as
-
-		man Tcl
-
-2b. Windows Documentation
--------------------------
-
-The "doc" subdirectory in this release contains a complete set of Windows
-help files for Tcl.  Once you install this Tcl release, a shortcut to the
-Windows help Tcl documentation will appear in the "Start" menu:
-
-	Start | Programs | Tcl | Tcl Help
-
-3. Compiling and installing Tcl
--------------------------------
-
-There are brief notes in the unix/README, win/README, and macosx/README about
-compiling on these different platforms.  There is additional information
-about building Tcl from sources at
-
-	http://www.tcl.tk/doc/howto/compile.html
-
-4. Development tools
----------------------------
-
-ActiveState produces a high quality set of commercial quality development
-tools that is available to accelerate your Tcl application development.
-Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,
-static code checker, single-file wrapping utility, bytecode compiler and
-more.  More information can be found at
-
-	http://www.ActiveState.com/Tcl
-
-5. Tcl newsgroup
-----------------
-
-There is a USENET news group, "comp.lang.tcl", intended for the exchange of
-information about Tcl, Tk, and related applications.  The newsgroup is a
-great place to ask general information questions.  For bug reports, please
-see the "Support and bug fixes" section below.
-
-6. Tcl'ers Wiki
----------------
-
-A Wiki-based open community site covering all aspects of Tcl/Tk is at:
-
-	http://wiki.tcl.tk/
-
-It is dedicated to the Tcl programming language and its extensions.  A
-wealth of useful information can be found there.  It contains code
-snippets, references to papers, books, and FAQs, as well as pointers to
-development tools, extensions, and applications.  You can also recommend
-additional URLs by editing the wiki yourself.
-
-7. Mailing lists
-----------------
-
-Several mailing lists are hosted at SourceForge to discuss development or
-use issues (like Macintosh and Windows topics).  For more information and
-to subscribe, visit:
-
-	http://sourceforge.net/projects/tcl/
-
-and go to the Mailing Lists page.
-
-8. Support and Training
-------------------------
-
-We are very interested in receiving bug reports, patches, and suggestions
-for improvements.  We prefer that you send this information to us as
-tickets entered into our tracker at:
-
-	http://core.tcl.tk/tcl/reportlist
-
-We will log and follow-up on each bug, although we cannot promise a
-specific turn-around time.  Enhancements may take longer and may not happen
-at all unless there is widespread support for them (we're trying to
-slow the rate at which Tcl/Tk turns into a kitchen sink).  It's very
-difficult to make incompatible changes to Tcl/Tk at this point, due to
-the size of the installed base.
-
-The Tcl community is too large for us to provide much individual support
-for users.  If you need help we suggest that you post questions to
-comp.lang.tcl.  We read the newsgroup and will attempt to answer esoteric
-questions for which no one else is likely to know the answer.  In addition,
-see the following Web site for links to other organizations that offer
-Tcl/Tk training:
-
-	http://wiki.tcl.tk/training
-
-9. Tracking Development
------------------------
-
-Tcl is developed in public.  To keep an eye on how Tcl is changing, see
-	http://core.tcl.tk/
-
-10. Thank You
--------------
-
-We'd like to express our thanks to the Tcl community for all the
-helpful suggestions, bug reports, and patches we have received.
-Tcl/Tk has improved vastly and will continue to do so with your help.

+A Tcl expression consists of a combination of operands, operators,

+parentheses (or commas); it is ignored by the expression's instructions.
+Where possible, operands are interpreted as integer values.
+Integer values may be specified in decimal (the normal case), in binary

+compatibility with older Tcl releases, an octal integer value is also
+indicated simply when the first character of the operand is \fB0\fR,
+whether or not the second character is also \fBo\fR.
+If an operand does not have one of the integer formats given
+above, then it is treated as a floating-point number if that is
+possible.  Floating-point numbers may be specified in any of several
+common formats making use of the decimal digits, the decimal point \fB.\fR,

+.PP
+String values may be used as operands of the comparison operators,
+although the expression evaluator tries to do comparisons as integer
+or floating-point when it can,
+i.e., when all arguments to the operator allow numeric interpretations,
+except in the case of the \fBeq\fR and \fBne\fR operators.
+If one of the operands of a comparison is a string and the other
+has a numeric value, a canonical string representation of the numeric
+operand value is generated to compare with the string operand.
+Canonical string representation for integer values is a decimal string

+is that produced by the \fB%g\fR format specifier of Tcl's
+\fBformat\fR command.  For example, the commands

+comparison, and the second is done using string comparison.
+Because of Tcl's tendency to treat values as numbers whenever
+possible, it is not generally a good idea to use operators like \fB==\fR
+when you really want string comparison and the values of the
+operands could be arbitrary;  it is better in these cases to use
+the \fBeq\fR or \fBne\fR operators, or the \fBstring\fR command instead.
 .SH "PERFORMANCE CONSIDERATIONS"
 .PP
-Where an expression contains syntax that Tcl would otherwise perform
-substitutions on, enclosing an expression in braces or otherwise quoting it
-so that it's a static value allows the Tcl compiler to generate bytecode for
-the expression, resulting in better speed and smaller storage requirements.
-This also avoids issues that can arise if Tcl is allowed to perform
-substitution on the value before \fBexpr\fR is called.
+Enclose expressions in braces for the best speed and the smallest
+storage requirements.
+This allows the Tcl bytecode compiler to generate the best code.
+.PP
+As mentioned above, expressions are substituted twice:
+once by the Tcl parser and once by the \fBexpr\fR command.
+For example, the commands
 .PP
-In the following example, the value of the expression is 11 because the Tcl parser first
-substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR.  Enclosing the
-expression in braces would result in a syntax error.

 .PP
-
-When an expression is generated at runtime, like the one above is, the bytcode
-compiler must ensure that new code is generated each time the expression
-is evaluated.  This is the most costly kind of expression from a performance
-perspective.  In such cases, consider directly using the commands described in
-the \fBmathfunc\fR(n) or \fBmathop\fR(n) documentation instead of \fBexpr\fR.
-
-Most expressions are not formed at runtime, but are literal strings or contain
-substitutions that don't introduce other substitutions.  To allow the bytecode
-compiler to work with an expression as a string literal at compilation time,
-ensure that it contains no substitutions or that it is enclosed in braces or
-otherwise quoted to prevent Tcl from performing substitutions, allowing
-\fBexpr\fR to perform them instead.
+return 11, not a multiple of 4.
+This is because the Tcl parser will first substitute \fB$a + 2\fR for
+the variable \fBb\fR,
+then the \fBexpr\fR command will evaluate the expression \fB$a + 2*4\fR.
+.PP
+Most expressions do not require a second round of substitutions.
+Either they are enclosed in braces or, if not,
+their variable and command substitutions yield numbers or strings
+that do not themselves require substitutions.
+However, because a few unbraced expressions
+need two rounds of substitutions,
+the bytecode compiler must emit
+additional instructions to handle this situation.
+The most expensive code is required for
+unbraced expressions that contain command substitutions.
+These expressions must be implemented by generating new code
+each time the expression is executed.
+When the expression is unbraced to allow the substitution of a function or
+operator, consider using the commands documented in the \fBmathfunc\fR(n) or
+\fBmathop\fR(n) manual pages directly instead.

+.SS "SPECIAL CASES"
+.PP
+This subsection discusses issues related to closure of the
+persistent connection by the server, automatic retry of failed requests,
+the special treatment necessary for POST requests, and the options for
+dealing with these cases.
+.PP
+In accordance with RFC 7230, \fBhttp::geturl\fR does not pipeline
+requests that use the POST method.  If a POST uses a persistent
+connection and is not the first request on that connection,
+\fBhttp::geturl\fR waits until it has received the response for the previous
+request; or (if \fBhttp::config\fR option \fB-postfresh\fR is boolean \fBtrue\fR) it
+uses a new connection for each POST.
+.PP
+If the server is processing a number of pipelined requests, and sends a
+response header
+.QW "\fBConnection: close\fR"
+with one of the responses (other than the last), then subsequent responses
+are unfulfilled. \fBhttp::geturl\fR will send the unfulfilled requests again
+over a new connection.
+.PP
+A difficulty arises when a HTTP client sends a request over a persistent
+connection that has been idle for a while.  The HTTP server may
+half-close an apparently idle connection while the client is sending a
+request, but before the request arrives at the server: in this case (an
+.QW "asynchronous close event" )
+the request will fail.  The difficulty arises because the client cannot
+be certain whether the POST modified the state of the server.  For HEAD or
+GET requests, \fBhttp::geturl\fR opens another connection and retransmits
+the failed request. However, if the request was a POST, RFC 7230 forbids
+automatic retry by default, suggesting either user confirmation, or
+confirmation by user-agent software that has semantic understanding of
+the application.  The \fBhttp::config\fR option \fB-repost\fR allows for
+either possibility.
+.PP
+Asynchronous close events can occur only in a short interval of time.  The
+\fBhttp\fR package monitors each persistent connection for closure by the
+server.  Upon detection, the connection is also closed at the client end,
+and subsequent requests will use a fresh connection.
+.PP
+If the \fBhttp::geturl\fR command is called with option \fB-keepalive true\fR,
+then it will both try to use an existing persistent connection
+(if one is available), and it will send the server a
+.QW "\fBConnection: keep-alive\fR"
