+== 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-2.2.5 is the source directory of expat, add a subdirectory
+build and change into that directory:
+~/expat-2.2.5$ mkdir build && cd build
+~/expat-2.2.5/build$
+
+From that directory, call cmake first, then call make, make test and 
+make install in the usual way:
+~/expat-2.2.5/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-2.2.5/build
+
+If you want to specify the install location for your files, append 
+-DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.
+
+~/expat-2.2.5/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 10" && vcexpress expat.sln
+for mingw builds do: 
+cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=D:\expat-install 
+    && gmake && gmake install

+                    it wanted to have.
+             #11  The default handler wasn't being called when it should for
+                    a SYSTEM or PUBLIC doctype if an entity declaration handler

+# Expat, Release 2.2.5
+
+This is Expat, a C library for parsing XML, started by
+[James Clark](https://en.wikipedia.org/wiki/James_Clark_(programmer)) 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.
+
+Windows users should use the
+[`expat_win32` package](https://sourceforge.net/projects/expat/files/expat_win32/),
+which includes both precompiled 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.
+
+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.
+
+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 &mdash; e.g. as part of
+a Linux distribution &mdash; 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.

+ * siphash.h - SipHash-2-4 in a single header file
+ * --------------------------------------------------------------------------
+ * Derived by William Ahern from the reference implementation[1] published[2]
+ * by Jean-Philippe Aumasson and Daniel J. Berstein.
+ * Minimal changes by Sebastian Pipping and Victor Stinner on top, see below.
+ * Licensed under the CC0 Public Domain Dedication license.
+ *
+ * 1. https://www.131002.net/siphash/siphash24.c
+ * 2. https://www.131002.net/siphash/
+ * --------------------------------------------------------------------------
+ * HISTORY:
+ *
+ * 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.

+
+Expat can be built on Windows in two ways:
+  using MS Visual Studio .NET or Cygwin.
+
+* Cygwin:
+  This follows the Unix build procedures.
+
+* MS Visual Studio 2013, 2015 and 2017:
+  A solution file for Visual Studio 2013 is provided: expat.sln.
+  The associated project files (*.vcxproj) reside in the appropriate
+  project directories. This solution file can be opened in VS 2015 or VS 2017
+  and should be upgraded automatically if VS 2013 is not also installed.
+  Note: Tests have their own solution files.
+
+* All MS C/C++ compilers:
+  The output for all projects will be generated in the win32\bin
+  directory, intermediate files will be located in project-specific
+  subdirectories of win32\tmp.
+  
+* Creating MinGW dynamic libraries from MS VC++ DLLs:
+  
+  On the command line, execute these steps:
+  pexports libexpat.dll > expat.def
+  pexports libexpatw.dll > expatw.def
+  dlltool -d expat.def -l libexpat.a
+  dlltool -d expatw.def -l libexpatw.a
+  
+  The *.a files are mingw libraries.
+
+* Special note about MS VC++ and runtime libraries:
+
+  There are three possible configurations: using the
+  single threaded or multithreaded run-time library,
+  or using the multi-threaded run-time Dll. That is, 
+  one can build three different Expat libraries depending
+  on the needs of the application.
+
+  Dynamic Linking:
+
+  By default the Expat Dlls are built to link statically
+  with the multi-threaded run-time library. 
+  The libraries are named
+  - libexpat(w).dll 
+  - libexpat(w).lib (import library)
+  The "w" indicates the UTF-16 version of the library.
+
+  One rarely uses other versions of the Dll, but they can
+  be built easily by specifying a different RTL linkage in
+  the IDE on the C/C++ tab under the category Code Generation.
+
+  Static Linking:
+
+  The libraries should be named like this:
+  Single-theaded:     libexpat(w)ML.lib
+  Multi-threaded:     libexpat(w)MT.lib
+  Multi-threaded Dll: libexpat(w)MD.lib
+  The suffixes conform to the compiler switch settings
+  /ML, /MT and /MD for MS VC++.
+  
+  Note: In Visual Studio 2005 (Visual C++ 8.0) and later, the
+  single-threaded runtime library is not supported anymore.
+
+  By default, the expat-static and expatw-static projects are set up
+  to link statically against the multithreaded run-time library,
+  so they will build libexpatMT.lib or libexpatwMT.lib files.
+
+  To build the other versions of the static library, 
+  go to Project - Settings:
+  - specify a different RTL linkage on the C/C++ tab
+    under the category Code Generation.
+  - then, on the Library tab, change the output file name
+    accordingly, as described above
+
+  An application linking to the static libraries must
+  have the global macro XML_STATIC defined.

+WelcomeLabel1=Welcome to the Expat XML Parser Setup Wizard
+WelcomeLabel2=This will install [name/ver] on your computer.%n%nExpat is an XML parser with a C-language API, and is primarily made available to allow developers to build applications which use XML using a portable API and fast implementation.%n%nIt is strongly recommended that you close all other applications you have running before continuing. This will help prevent any conflicts during the installation process.
