+SUMMARY
+=======
+This is a port of expat for AmigaOS 4.x which includes the
+SDK, some XML tools and the libraries.
+
+Four library flavours are supported:
+1. static clib2 (libexpat.a)
+2. static newlib (libexpat.a)
+3. AmigaOS library (expat.library)
+4. AmigaOS shared object library (libexpat.so)
+
+The AmigaOS library version is based on the work of Fredrik Wikstrom.
+
+
+BUILDING
+========
+To build all the library flavours, all the tools, examples and run the
+test suite, simply type 'make all' in the amiga subdirectory.
+
+
+INSTALLATION
+============
+To install expat into the standard AmigaOS SDK type 'make install'
+in the amiga subdirectory.
+
+
+CONFIGURATION
+=============
+You may want to edit the lib/amigaconfig.h file to remove
+DTD and/or XML namespace support if they are not required by your
+specific application for a smaller and faster implementation.
+
+
+SOURCE CODE
+===========
+The source code is actively maintained and merged with the official
+Expat repository available at http://expat.sourceforge.net/
+
+
+HISTORY
+=======
+53.1 - bumped version to match AmigaOS streaming
+     - modified to remove all global variables (except INewLib)
+     - removed replacements for malloc(), etc. which are now
+       handled by the respective C library
+     - compiled with the latest binutils which bumps the
+       AMIGAOS_DYNVERSION to 2 for the libexpat.so target
+     - now strips the expat.library binary
+
+5.2  - fixed XML_Parse 68k stub which enables xmlviewer to work
+       without crashing
+     - added some new functions to the 68k jump table available
+       in the latest expat.library for AmigaOS 3.x
+     - patches provided by Fredrik Wikstrom
+
+5.1  - fixed package archive which was missing libexpat.so
+     - fixed library protection bits
+     - fixed up copyright notices
+
+5.0  - integrated 68k patches from Fredrik Wikstrom which means
+       expat.library is now callable from 68k code
+     - bumped version for the addition of the 68k interface so
+       executables can explicitly ask for version 5 and know
+       it includes the 68k interface
+     - refactored Makefile to avoid recursive make calls and
+       build all the library flavours
+     - added static newlib version
+     - added shared objects version
+     - added package target to Makefile
+     - compiled with SDK 53.13 (GCC 4.2.4) at -O3

+     - modified launch.c to use contructor/deconstructor
+     - removed need for amiga_main() from expat utilities
+
+4.1  - fixed memory freeing bug in shared library version
+     - now allocates shared memory
