 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 kB (using gcc or Visual C on a i386), and
 the sources are about 30 kB 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

 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(char *) != sizeof(long)'.
 After identifying the problem you can compile by adding some defines
 like `-DSIZEOF_CHAR_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.in.
