+ ============================================================================
+ miniLZO -- mini subset of the LZO real-time data compression library
+ ============================================================================
+
+ Author : Markus Franz Xaver Johannes Oberhumer
+ <markus@oberhumer.com>
+ http://www.oberhumer.com/opensource/lzo/
+ Version : 2.08
+ Date : 29 Jun 2014
+
+ I've created miniLZO for projects where it is inconvenient to
+ include (or require) the full LZO source code just because you
+ want to add a little bit of data compression to your application.
+
+ miniLZO implements the LZO1X-1 compressor and both the standard and
+ safe LZO1X decompressor. Apart from fast compression it also useful
+ for situations where you want to use pre-compressed data files (which
+ must have been compressed with LZO1X-999).
+
+ miniLZO consists of one C source file and three header files:
+ minilzo.c
+ minilzo.h, lzoconf.h, lzodefs.h
+
+ To use miniLZO just copy these files into your source directory, add
+ minilzo.c to your Makefile and #include minilzo.h from your program.
+ Note: you also must distribute this file ('README.LZO') with your project.
+
+ minilzo.o compiles to about 6 KiB (using gcc or Visual C on an i386), and
+ the sources are about 30 KiB when packed with zip - so there's no more
+ excuse that your application doesn't support data compression :-)
+
+ For more information, documentation, example programs and other support
+ files (like Makefiles and build scripts) please download the full LZO
+ package from
+ http://www.oberhumer.com/opensource/lzo/
+
+ Have fun,
+ Markus
+
+
+ P.S. minilzo.c is generated automatically from the LZO sources and
+ therefore functionality is completely identical
+
+
+ Appendix A: building miniLZO
+ ----------------------------
+ miniLZO is written such a way that it should compile and run
+ out-of-the-box on most machines.
+
+ If you are running on a very unusual architecture and lzo_init() fails then
+ you should first recompile with '-DLZO_DEBUG' to see what causes the failure.
+ The most probable case is something like 'sizeof(void *) != sizeof(size_t)'.
+ After identifying the problem you can compile by adding some defines
+ like '-DSIZEOF_VOID_P=8' to your Makefile.
+
+ The best solution is (of course) using Autoconf - if your project uses
+ Autoconf anyway just add '-DMINILZO_HAVE_CONFIG_H' to your compiler
+ flags when compiling minilzo.c. See the LZO distribution for an example
+ how to set up configure.ac.
