 ============================================================================

 miniLZO -- mini subset of the LZO real-time data compression library

 ============================================================================



 Author  : Markus Franz Xaver Johannes Oberhumer

           

           http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html

 Version : 1.07

 Date    : 18-Oct-2000



 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 two header files:

    minilzo.c

    minilzo.h

    lzoconf.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 Watcom C on a i386), and

 the sources are about 14 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

    http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html



 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.
