 ============================================================================
 miniLZO -- mini version of the LZO real-time data compression library
 ============================================================================

 Author  : Markus Franz Xaver Johannes Oberhumer

 Version : 1.00
 Date    : 13-Jul-1997

 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
    ../include/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.

 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 and other support files (like Makefiles
 and build scripts) please download the full LZO package from
    http://www.infosys.tuwien.ac.at/Staff/lux/marco/lzo.html

 Have fun,
  Markus



 Appendix A: building miniLZO
 ----------------------------
 miniLZO is written such a way that it (hopefully) should compile
 and run out-of-the box on most machines.

 If you are running on an 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 that sizeof(char *) != sizeof(long).

 After identifying the problem you can workaround 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. See the LZO distribution for an example how to set up `configure.in'.

 Checksum functions
    lzo_adler32()

 Version functions
    lzo_version()
    lzo_version_string()
    lzo_version_date()

 Portable (but slow) string functions
