+== How to build expat with cmake (experimental) ==
+
+The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual
+Studio) and should work on all other platform cmake supports.
+
+Assuming ~/expat-2.5.0 is the source directory of expat, add a subdirectory
+build and change into that directory:
+~/expat-2.5.0$ mkdir build && cd build
+~/expat-2.5.0/build$
+
+From that directory, call cmake first, then call make, make test and
+make install in the usual way:
+~/expat-2.5.0/build$ cmake ..
+-- The C compiler identification is GNU
+-- The CXX compiler identification is GNU
+....
+-- Configuring done
+-- Generating done
+-- Build files have been written to: /home/patrick/expat-2.5.0/build
+
+If you want to specify the install location for your files, append
+-DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.
+
+~/expat-2.5.0/build$ make && make test && make install
+Scanning dependencies of target expat
+[  5%] Building C object CMakeFiles/expat.dir/lib/xmlparse.c.o
+[ 11%] Building C object CMakeFiles/expat.dir/lib/xmlrole.c.o
+....
+-- Installing: /usr/local/lib/pkgconfig/expat.pc
+-- Installing: /usr/local/bin/xmlwf
+-- Installing: /usr/local/share/man/man1/xmlwf.1
+
+For Windows builds, you must make sure to call cmake from an environment where
+your compiler is reachable, that means either you call it from the
+Visual Studio Command Prompt or when using mingw, you must open a cmd.exe and
+make sure that gcc can be called. On Windows, you also might want to specify a
+special Generator for CMake:
+for Visual Studio builds do:
+cmake .. -G "Visual Studio 15 2017" && msbuild /m expat.sln
+for mingw builds do:
+cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=D:\expat-install
+    && gmake && gmake install

+    # Macro expat_shy_set came into life because:
+    # - Expat was previously using an inconsistent mix of CMake's native set()
+    #   and option() to define public build time options.
+    # - option() is more friendly than set() with regard to configuring an
+    #   external project that is pulled in by means of add_subdirectory() --
+    #   see comments in issue #597 -- so we wanted to get away from set().
+    # - option() auto-converts non-bool values to bool when writing to the CMake
+    #   cache, so we needed something that supports non-bool better and hence
+    #   wanted to get away from plain option(), too.
+    #
+    # As a result, this function serves as a hybrid between CMake's regular set()
+    # and option(): from set() it takes support for non-bool types and the function
+    # name and signature whereas from option() (with policy CMP0077 mode NEW) it
+    # takes being shy when a value has previously been defined for that variable.
+    #

+# Expat, Release 2.5.0
+
+This is Expat, a C library for parsing XML, started by
+[James Clark](https://en.wikipedia.org/wiki/James_Clark_%28programmer%29) in 1997.
+Expat is a stream-oriented XML parser.  This means that you register
+handlers with the parser before starting the parse.  These handlers
+are called when the parser discovers the associated structures in the
+document being parsed.  A start tag is an example of the kind of
+structures for which you may register handlers.
+
+Expat supports the following compilers:
+
+- GNU GCC >=4.5
+- LLVM Clang >=3.5
+- Microsoft Visual Studio >=15.0/2017 (rolling `${today} minus 5 years`)
+
+Windows users can use the
+[`expat-win32bin-*.*.*.{exe,zip}` download](https://github.com/libexpat/libexpat/releases),
+which includes both pre-compiled libraries and executables, and source code for
+developers.
+
+Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
+You may copy, distribute, and modify it under the terms of the License
+contained in the file
+[`COPYING`](https://github.com/libexpat/libexpat/blob/master/expat/COPYING)
+distributed with this package.
+This license is the same as the MIT/X Consortium license.
+
+
+## Using libexpat in your CMake-Based Project
+
+There are two ways of using libexpat with CMake:
+
+### a) Module Mode
+
+This approach leverages CMake's own [module `FindEXPAT`](https://cmake.org/cmake/help/latest/module/FindEXPAT.html).
+
+Notice the *uppercase* `EXPAT` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)  # or 3.10, see below
+
+project(hello VERSION 1.0.0)
+
+find_package(EXPAT 2.2.8 MODULE REQUIRED)
+
+add_executable(hello
+    hello.c
+)
+
+# a) for CMake >=3.10 (see CMake's FindEXPAT docs)
+target_link_libraries(hello PUBLIC EXPAT::EXPAT)
+
+# b) for CMake >=3.0
+target_include_directories(hello PRIVATE ${EXPAT_INCLUDE_DIRS})
+target_link_libraries(hello PUBLIC ${EXPAT_LIBRARIES})
+```
+
+### b) Config Mode
+
+This approach requires files from…
+
+- libexpat >=2.2.8 where packaging uses the CMake build system
+or
+- libexpat >=2.3.0 where packaging uses the GNU Autotools build system
+  on Linux
+or
+- libexpat >=2.4.0 where packaging uses the GNU Autotools build system
+  on macOS or MinGW.
+
+Notice the *lowercase* `expat` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)
+
+project(hello VERSION 1.0.0)
+
+find_package(expat 2.2.8 CONFIG REQUIRED char dtd ns)
+
+add_executable(hello
+    hello.c
+)
+
+target_link_libraries(hello PUBLIC expat::expat)
+```
+
+
+## Building from a Git Clone
+
+If you are building Expat from a check-out from the
+[Git repository](https://github.com/libexpat/libexpat/),
+you need to run a script that generates the configure script using the
+GNU autoconf and libtool tools.  To do this, you need to have
+autoconf 2.58 or newer. Run the script like this:
+
+```console
+./buildconf.sh
+```
+
+Once this has been done, follow the same instructions as for building
+from a source distribution.
+
+
+## Building from a Source Distribution
+
+### a) Building with the configure script (i.e. GNU Autotools)
+
+To build Expat from a source distribution, you first run the
+configuration shell script in the top level distribution directory:
+
+```console
+./configure
+```
+
+There are many options which you may provide to configure (which you
+can discover by running configure with the `--help` option).  But the
+one of most interest is the one that sets the installation directory.
+By default, the configure script will set things up to install
+libexpat into `/usr/local/lib`, `expat.h` into `/usr/local/include`, and
+`xmlwf` into `/usr/local/bin`.  If, for example, you'd prefer to install
+into `/home/me/mystuff/lib`, `/home/me/mystuff/include`, and
+`/home/me/mystuff/bin`, you can tell `configure` about that with:
+
+```console
+./configure --prefix=/home/me/mystuff
+```
+
+Another interesting option is to enable 64-bit integer support for
+line and column numbers and the over-all byte index:
+
+```console
+./configure CPPFLAGS=-DXML_LARGE_SIZE
+```
+
+However, such a modification would be a breaking change to the ABI
+and is therefore not recommended for general use — e.g. as part of
+a Linux distribution — but rather for builds with special requirements.
+
+After running the configure script, the `make` command will build
+things and `make install` will install things into their proper
+location.  Have a look at the `Makefile` to learn about additional
+`make` options.  Note that you need to have write permission into
+the directories into which things will be installed.
+
+If you are interested in building Expat to provide document
+information in UTF-16 encoding rather than the default UTF-8, follow
+these instructions (after having run `make distclean`).
+Please note that we configure with `--without-xmlwf` as xmlwf does not
+support this mode of compilation (yet):
+
+1. Mass-patch `Makefile.am` files to use `libexpatw.la` for a library name:
+   <br/>
+   `find -name Makefile.am -exec sed
+       -e 's,libexpat\.la,libexpatw.la,'
+       -e 's,libexpat_la,libexpatw_la,'
+       -i {} +`
+
+1. Run `automake` to re-write `Makefile.in` files:<br/>
+   `automake`
+
+1. For UTF-16 output as unsigned short (and version/error strings as char),
+   run:<br/>
+   `./configure CPPFLAGS=-DXML_UNICODE --without-xmlwf`<br/>
+   For UTF-16 output as `wchar_t` (incl. version/error strings), run:<br/>
+   `./configure CFLAGS="-g -O2 -fshort-wchar" CPPFLAGS=-DXML_UNICODE_WCHAR_T
+       --without-xmlwf`
+   <br/>Note: The latter requires libc compiled with `-fshort-wchar`, as well.
+
+1. Run `make` (which excludes xmlwf).
+
+1. Run `make install` (again, excludes xmlwf).
+
+Using `DESTDIR` is supported.  It works as follows:
+
+```console
+make install DESTDIR=/path/to/image
+```
+
+overrides the in-makefile set `DESTDIR`, because variable-setting priority is
+
+1. commandline
+1. in-makefile
+1. environment
+
+Note: This only applies to the Expat library itself, building UTF-16 versions
+of xmlwf and the tests is currently not supported.
+
+When using Expat with a project using autoconf for configuration, you
+can use the probing macro in `conftools/expat.m4` to determine how to
+include Expat.  See the comments at the top of that file for more
+information.
+
+A reference manual is available in the file `doc/reference.html` in this
+distribution.
+
+
+### b) Building with CMake
+
+The CMake build system is still *experimental* and may replace the primary
+build system based on GNU Autotools at some point when it is ready.
+
+
+#### Available Options
+
+For an idea of the available (non-advanced) options for building with CMake:
+
+```console
+# rm -f CMakeCache.txt ; cmake -D_EXPAT_HELP=ON -LH . | grep -B1 ':.*=' | sed 's,^--$,,'
+// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
+CMAKE_BUILD_TYPE:STRING=
+
+// Install path prefix, prepended onto install directories.
+CMAKE_INSTALL_PREFIX:PATH=/usr/local

+# Style guidelines for `configure.ac`
+
+Version `2019.08.09.21.54`
+
+
+## Purpose
+
+Define a small set of rules for style used in Expat's `configure.ac`
+so that we have a common ground and something documented to refer to
+in pull requests, when style is off.
+
+
+## 1. Quoting
+Quote "everything":
+```
+AC_DEFINE([HAVE_FOO], [1], [Define to 1 if you have the `foo' function.])
+```
+
+## 2. Parameter indentation
+
+Parameters to functions either go
+- (a) on the the same line or
+- (b) align vertically or
+- (c) go to the next line, with the first character indented 2 spaces more
+  than the first *non-`[`*(!) parent level character,
+  i.e. 2 or [3 columns further right](https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Autoconf-Language.html):
+
+```
+CALL([parameter], [parameter], [parameter])
+
+CALL([parameter],
+     [parameter],
+     [parameter])
+
+CALL([parameter], [parameter],
+  [CALL(
+     [CALL()])])
+
+  ^  ^
+  |  2 + 3(!) spaces
+  2 spaces
+```
+
+## 3. Consecutive call / multi-line indentation
+
+Consecutive calls to macros (= on the the same nesting level) are aligned vertically:
+
+```
+CALL([parameter],
+  [CALL([])
+   CALL([])
+   CALL([])])
+```
+
+## 4. Closing bracket placement
+Closing braces accumulate on the same line in general...
+
+```
+CALL(
+  [CALL([CALL([])],
+        [CALL([])])
+   CALL([])])
+```
+
+...but can go a new line (e.g. with `AC_LANG_SOURCE`) to match parameter indentation rule (2), i.e. either
+
+```
+CALL([CALL([
+    one
+    two
+  ])],
+  [CALL()])
+```
+
+.. or ..
+```
+CALL([CALL([
+        one
+        two
+     ])],
+     [CALL()])
+```

+#   It's like AC_REQUIRE except it doesn't expand the required macro.

+    <title>DESCRIPTION</title>
+
+    <para>
+	<command>&dhpackage;</command> uses the Expat library to
+	determine if an XML document is well-formed.  It is
+	non-validating.
+	</para>
+
+	<para>
+	If you do not specify any files on the command-line, and you
+	have a recent version of <command>&dhpackage;</command>, the
+	input file will be read from standard input.
+	</para>
+
+  </refsect1>
+
+  <refsect1>
+    <title>WELL-FORMED DOCUMENTS</title>
+
+	<para>
+	  A well-formed document must adhere to the
+	  following rules:
+	</para>
+
+	<itemizedlist>
+      <listitem><para>
+	    The file begins with an XML declaration.  For instance,
+		<literal>&lt;?xml version="1.0" standalone="yes"?&gt;</literal>.
+		<emphasis>NOTE</emphasis>:
+		<command>&dhpackage;</command> does not currently
+		check for a valid XML declaration.
+      </para></listitem>
+      <listitem><para>
+		Every start tag is either empty (&lt;tag/&gt;)
+		or has a corresponding end tag.
+      </para></listitem>
+      <listitem><para>
+	    There is exactly one root element.  This element must contain
+		all other elements in the document.  Only comments, white
+		space, and processing instructions may come after the close
+		of the root element.
+      </para></listitem>
+      <listitem><para>
+		All elements nest properly.
+      </para></listitem>
+      <listitem><para>
+		All attribute values are enclosed in quotes (either single
+		or double).
+      </para></listitem>
+    </itemizedlist>
+
+	<para>
+	  If the document has a DTD, and it strictly complies with that
+	  DTD, then the document is also considered <emphasis>valid</emphasis>.
+	  <command>&dhpackage;</command> is a non-validating parser --
+	  it does not check the DTD.  However, it does support
+	  external entities (see the <option>-x</option> option).
+	</para>
+  </refsect1>
+
+  <refsect1>
+    <title>OPTIONS</title>
+
+<para>
+When an option includes an argument, you may specify the argument either
+separately ("<option>-d</option> <replaceable>output</replaceable>") or concatenated with the
+option ("<option>-d</option><replaceable>output</replaceable>").  <command>&dhpackage;</command>
+supports both.
+</para>
+
+    <variablelist>
+
+      <varlistentry>
+        <term><option>-a</option> <replaceable>factor</replaceable></term>
+        <listitem>
+          <para>
+            Sets the maximum tolerated amplification factor
+            for protection against billion laughs attacks (default: 100.0).
+            The amplification factor is calculated as ..
+          </para>
+          <literallayout>
+            amplification := (direct + indirect) / direct
+          </literallayout>
+          <para>
+            .. while parsing, whereas
+            &lt;direct&gt; is the number of bytes read
+              from the primary document in parsing and
+            &lt;indirect&gt; is the number of bytes
+              added by expanding entities and reading of external DTD files,
+              combined.
+          </para>
+          <para>
+            <emphasis>NOTE</emphasis>:
+            If you ever need to increase this value for non-attack payload,
+            please file a bug report.
+          </para>

+        <listitem>
+          <para>
+            Sets the number of output bytes (including amplification)
+            needed to activate protection against billion laughs attacks
+            (default: 8 MiB).
+            This can be thought of as an &quot;activation threshold&quot;.
+          </para>
+          <para>
+            <emphasis>NOTE</emphasis>:
+            If you ever need to increase this value for non-attack payload,

+      <varlistentry>
+        <term><option>-c</option></term>
+        <listitem>
+		<para>
+  If the input file is well-formed and <command>&dhpackage;</command>
+  doesn't encounter any errors, the input file is simply copied to
+  the output directory unchanged.
+  This implies no namespaces (turns off <option>-n</option>) and
+  requires <option>-d</option> to specify an output directory.
+  		</para>
+        </listitem>
+      </varlistentry>
+
+      <varlistentry>
+        <term><option>-d</option> <replaceable>output-dir</replaceable></term>
+        <listitem>
+		<para>
+  Specifies a directory to contain transformed
+  representations of the input files.
+  By default, <option>-d</option> outputs a canonical representation
+  (described below).
+  You can select different output formats using <option>-c</option>,
+  <option>-m</option> and <option>-N</option>.
+	  </para>
+	  <para>
+  The output filenames will
+  be exactly the same as the input filenames or "STDIN" if the input is
+  coming from standard input.  Therefore, you must be careful that the
+  output file does not go into the same directory as the input
+  file.  Otherwise, <command>&dhpackage;</command> will delete the
+  input file before it generates the output file (just like running
+  <literal>cat &lt; file &gt; file</literal> in most shells).
+	  </para>
+	  <para> 
+  Two structurally equivalent XML documents have a byte-for-byte
+  identical canonical XML representation.
+  Note that ignorable white space is considered significant and
+  is treated equivalently to data.
+  More on canonical XML can be found at
+  http://www.jclark.com/xml/canonxml.html .

+        <listitem>
+		<para>
+   Specifies the character encoding for the document, overriding
+   any document encoding declaration.  <command>&dhpackage;</command>
+   supports four built-in encodings:
+   	<literal>US-ASCII</literal>,
+	<literal>UTF-8</literal>,
+	<literal>UTF-16</literal>, and
+	<literal>ISO-8859-1</literal>.
+   Also see the <option>-w</option> option.

+        <listitem>
+          <para>
+            When processing multiple files, <command>&dhpackage;</command>
+            by default halts after the the first file with an error.
+            This tells <command>&dhpackage;</command> to report the error
+            but to keep processing.
+            This can be useful, for example, when testing a filter that converts
+            many files to XML and you want to quickly find out which conversions
+            failed.
+          </para>

+    entities.
+	 </para>
+	 <para>
+   Normally <command>&dhpackage;</command> never parses parameter

+        <listitem>
+		<para>
+   Normally <command>&dhpackage;</command> memory-maps the XML file
+   before parsing; this can result in faster parsing on many
+   platforms.
+   <option>-r</option> turns off memory-mapping and uses normal file
+   IO calls instead.
+   Of course, memory-mapping is automatically turned off
+   when reading from standard input.
+	   </para>
+		<para>
+   Use of memory-mapping can cause some platforms to report
+   substantially higher memory usage for
+   <command>&dhpackage;</command>, but this appears to be a matter of
+   the operating system reporting memory in a strange way; there is
+   not a leak in <command>&dhpackage;</command>.

+      </varlistentry>
+
+      <varlistentry>
+        <term><option>-s</option></term>
+        <listitem>
+		<para>

+  A document is standalone if it has no external subset and no
+  references to parameter entities.

+  Turns on parsing external entities.
+  </para>
+<para>
+  Non-validating parsers are not required to resolve external
+  entities, or even expand entities at all.
+  Expat always expands internal entities (?),
+  but external entity parsing must be enabled explicitly.
+  </para>
+  <para>
+  External entities are simply entities that obtain their
+  data from outside the XML file currently being parsed.
+  </para>
+  <para>
+  This is an example of an internal entity:
+<literallayout>
+&lt;!ENTITY vers '1.0.2'&gt;
+</literallayout>
+  </para>
+  <para>
+  And here are some examples of external entities:
+
+<literallayout>
+&lt;!ENTITY header SYSTEM "header-&amp;vers;.xml"&gt;  (parsed)
+&lt;!ENTITY logo SYSTEM "logo.png" PNG&gt;         (unparsed)

+        <term><option>--</option></term>
+        <listitem>
+		<para>
+    (Two hyphens.)
+    Terminates the list of options.  This is only needed if a filename
+    starts with a hyphen.  For example:
+	   </para>
+<literallayout>
+&dhpackage; -- -myfile.xml
+</literallayout>
+		<para>
+    will run <command>&dhpackage;</command> on the file
+    <filename>-myfile.xml</filename>.

+

+    Older versions of <command>&dhpackage;</command> do not support
+    reading from standard input.
+	</para>
+  </refsect1>
+
+  <refsect1>
+  <title>OUTPUT</title>
+    <para>
+	<command>&dhpackage;</command> outputs nothing for files which are problem-free.
+        If any input file is not well-formed, or if the output for any
+	input file cannot be opened, <command>&dhpackage;</command> prints a single
+	line describing	the problem to standard output.
+    </para>
+    <para>
+        If the <option>-k</option> option is not provided, <command>&dhpackage;</command>
+	halts upon encountering a well-formedness or output-file error. 
+	If <option>-k</option> is provided, <command>&dhpackage;</command> continues
+	processing the remaining input files, describing problems found with any of them.

+

+  <title>EXIT STATUS</title>
+    <para>For option <option>-v</option> or <option>-h</option>, <command>&dhpackage;</command> always exits with status code 0.  For other cases, the following exit status codes are returned:

-<P>The directory <SAMP>xmlparse</SAMP> contains an XML parser library
-which is built on top of the <SAMP>xmltok</SAMP> library.  The
-interface is documented in <SAMP>xmlparse/xmlparse.h</SAMP>.  The
-directory <SAMP>sample</SAMP> contains a simple example program using
-this interface; <SAMP>sample/build.bat</SAMP> is a batch file to build
-the example using Visual C++.</P>
-
-<P>The directory <SAMP>xmlwf</SAMP> contains the <SAMP>xmlwf</SAMP>
-application, which uses the <SAMP>xmlparse</SAMP> library. The
-arguments to <SAMP>xmlwf</SAMP> are one or more files which are each
-to be checked for well-formedness. An option <SAMP>-d
-<VAR>dir</VAR></SAMP> can be specified; for each well-formed input
-file the corresponding <A
-href="http://www.jclark.com/xml/canonxml.html">canonical XML</A> will
-be written to <SAMP>dir/<VAR>f</VAR></SAMP>, where
-<SAMP><VAR>f</VAR></SAMP> is the filename (without any path) of the
-input file.  A <CODE>-x</CODE> option will cause references to
-external general entities to be processed.  A <CODE>-s</CODE> option
-will make documents that are not standalone cause an error (a document
-is considered standalone if either it is intrinsically standalone
-because it has no external subset and no references to parameter
-entities in the internal subset or it is declared as standalone in the
-XML declaration).</P>

-<BODY>
-
-<H1>Frequently Asked Questions about Expat</H1>
-
-<H4>Where can I get the latest version of expat?</H4>
-
-<p>The latest production version is always available from <a
-href="http://www.ThaiOpenSource.com/dist/expat"
->http://www.ThaiOpenSource.com/dist/expat</a>.  If there is a test
-version, then it will be available from <a
-href="http://www.ThaiOpenSource.com/dist/expat/test"
->http://www.ThaiOpenSource.com/dist/expat/test</a>.</p>
-
-<H4>Where can I get help in using expat?</H4>
-
-<p>Try the xml-dev mailing list (subscribe by mailing to <a
-href="mailto:majordomo@xml.org&BODY=subscribe%20xml-dev">majordomo@xml.org</a>
-with the message <code>subscribe xml-dev</code>).  Alternatively try
-the <a href="news:comp.text.xml">comp.text.xml</a> USENET
-newsgroup.</p>
-
-<H4>Where is expat's API documented?</H4>
-
-<p>In <code>xmlparse/xmlparse.h</code>.  There's also an advanced,
-low-level API you can use which is documented in
-<code>xmltok/xmltok.h</code>.</p>
-
-<p>There's also an excellent <a
-href="http://www.xml.com/pub/1999/09/expat/index.html">article</a>
-about expat on XML.com by Clark Cooper.</p>
-
-<H4>Is there a simple example of using expat's API?</H4>
-
-<p>See <code>sample/elements.c</code></p>
-
-<H4>How can I get expat to deal with non-ASCII characters?</H4>
-
-<P>By default, expat assumes that documents are encoded in UTF-8.  In
-UTF-8, ASCII characters are represented by a single byte as they would
-be in ASCII, but non-ASCII characters are represented by a sequence of
-two or more bytes all with the 8th bit set.  The encoding most widely
-used for European languages is ISO 8859-1 which is not compatible with
-UTF-8.  To use this encoding, expat must be told either by supplying
-an argument of <code>"iso-8859-1"</code> to
-<code>XML_ParserCreate</code>, or by starting the document with
-<code>&lt;?xml version="1.0" encoding="iso-8859-1"?&gt;</code>.</P>
-
-<H4>What encodings does expat support?</H4>
-
-<P>expat has built in support for the following encodings:</P>
-
-<ul>
-<li><code>utf-8</code></li>
-<li><code>utf-16</code></li>
-<li><code>iso-8859-1</code></li>
-<li><code>us-ascii</code></li>
-</ul>
-
-<P>Additional encodings can be supported by using
-<code>XML_SetUnknownEncodingHandler</code>.</P>
-
-<H4>How can I get expat to validate my XML documents?</H4>
-
-<p>You can't.  expat is not a validating parser.</p>
-
-<H4>How can I get expat to read my DTD?</H4>
-
-<p>Compile with <code>-DXML_DTD</code> and call
-<code>XML_SetParamEntityParsing</code>.</p>
-
-<H4>How can I get expat to recover from errors?</H4>
-
-<p>You can't.  All well-formedness errors stop processing.  Note that
-the XML Recommendation does not permit conforming XML processors to
-continue normal processing after a fatal error.</p>
-
-<H4>How do I get at the characters between tags?</H4>
-
-<p>Use <code>XML_SetCharacterDataHandler</code>.</p>
-
-<H4>How can I minimize the size of expat?</H4>
-
-<p>Compile with <code>-DXML_MIN_SIZE</code>. With Visual C++, use the
-<code>Win32 MinSize</code> configuration: this creates an
-<code>xmlparse.dll</code> that does not require
-<code>xmltok.dll</code>.</p>

+
+   XMLCALL    - The calling convention to use for all calls across the

+

+                to be imported from a dynamically loaded library
+                (.dll, .so, or .sl, depending on your platform).
+
+   The XMLCALL macro was added in Expat 1.95.7.  The only one which is
+   expected to be directly useful in client code is XMLCALL.
+
+   Note that on at least some Unix versions, the Expat library must be

+
+   FASTCALL    - Used for those internal functions that have a simple
+                 body and a low number of arguments and local variables.
+
+   PTRCALL     - Used for functions called though function pointers.
+
+   PTRFASTCALL - Like PTRCALL, but for low number of arguments.
+
+   inline      - Used for selected internal functions for which inlining
+                 may improve performance on some platforms.
+
+   Note: Use of these macros is based on judgement, not hard rules,
+         and therefore subject to change.

+ * --------------------------------------------------------------------------
+ * HISTORY:
+ *
+ * 2020-10-03  (Sebastian Pipping)
+ *   - Drop support for Visual Studio 9.0/2008 and earlier
+ *
+ * 2019-08-03  (Sebastian Pipping)
+ *   - Mark part of sip24_valid as to be excluded from clang-format
+ *   - Re-format code using clang-format 9
+ *
+ * 2018-07-08  (Anton Maklakov)
+ *   - Add "fall through" markers for GCC's -Wimplicit-fallthrough
+ *
+ * 2017-11-03  (Sebastian Pipping)
+ *   - Hide sip_tobin and sip_binof unless SIPHASH_TOBIN macro is defined
+ *
+ * 2017-07-25  (Vadim Zeitlin)
+ *   - Fix use of SIPHASH_MAIN macro
+ *
+ * 2017-07-05  (Sebastian Pipping)
+ *   - Use _SIP_ULL macro to not require a C++11 compiler if compiled as C++
+ *   - Add const qualifiers at two places
+ *   - Ensure <=80 characters line length (assuming tab width 4)
+ *
+ * 2017-06-23  (Victor Stinner)
+ *   - Address Win64 compile warnings
+ *
+ * 2017-06-18  (Sebastian Pipping)
+ *   - Clarify license note in the header
+ *   - Address C89 issues:
+ *     - Stop using inline keyword (and let compiler decide)
+ *     - Replace _Bool by int
+ *     - Turn macro siphash24 into a function
+ *     - Address invalid conversion (void pointer) by explicit cast
+ *   - Address lack of stdint.h for Visual Studio 2003 to 2008
+ *   - Always expose sip24_valid (for self-tests)
+ *
+ * 2012-11-04 - Born.  (William Ahern)
+ * --------------------------------------------------------------------------
+ * USAGE:
+ *
+ * SipHash-2-4 takes as input two 64-bit words as the key, some number of
+ * message bytes, and outputs a 64-bit word as the message digest. This
+ * implementation employs two data structures: a struct sipkey for
+ * representing the key, and a struct siphash for representing the hash
+ * state.
+ *
+ * For converting a 16-byte unsigned char array to a key, use either the
+ * macro sip_keyof or the routine sip_tokey. The former instantiates a
+ * compound literal key, while the latter requires a key object as a
+ * parameter.
+ *
+ * 	unsigned char secret[16];
+ * 	arc4random_buf(secret, sizeof secret);
+ * 	struct sipkey *key = sip_keyof(secret);
+ *
+ * For hashing a message, use either the convenience macro siphash24 or the
+ * routines sip24_init, sip24_update, and sip24_final.
+ *
+ * 	struct siphash state;
+ * 	void *msg;
+ * 	size_t len;
+ * 	uint64_t hash;
+ *
+ * 	sip24_init(&state, key);
+ * 	sip24_update(&state, msg, len);
+ * 	hash = sip24_final(&state);
+ *
+ * or
+ *
+ * 	hash = siphash24(msg, len, key);
+ *
+ * To convert the 64-bit hash value to a canonical 8-byte little-endian
+ * binary representation, use either the macro sip_binof or the routine
+ * sip_tobin. The former instantiates and returns a compound literal array,
+ * while the latter requires an array object as a parameter.
+ * --------------------------------------------------------------------------
+ * NOTES:
+ *
+ * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
+ *   lacking compound literal support. Instead, you must use the lower-level
+ *   interfaces which take as parameters the temporary state objects.
+ *
+ * o Uppercase macros may evaluate parameters more than once. Lowercase
+ *   macros should not exhibit any such side effects.
