 zlib 0.91 is a beta version of a general purpose compression library.

 The data format used by the zlib library is described in the
 files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
 in ftp.uu.net:/pub/archiving/zip/doc.

 All functions of the compression library are documented in the file
 zlib.h. A usage example of the library is given in the file example.c
 which also tests that the library is working correctly.

 To compile all files and run the test program, just type: make test
 (For MSDOS, use one of the special makefiles such as Makefile.msc.)
 To install the zlib library (libgz.a) in /usr/local/lib, type: make install
 To install in a different directory, use for example: make install prefix=$HOME
 This will install in $HOME/lib instead of /usr/local/lib.

 The changes made in version 0.91 are documented in the file ChangeLog.
 The main changes since 0.9 are:
 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
 - Document the memory requirements in zconf.h
 - added "make install"
 - added support for DJGPP

 On MSDOS, this version works in both large and small model. However
 small model compression works only for small values of MAX_MEM_LEVEL
 and MAX_WBITS (see zconf.h). Small model decompression should work up
 to MAX_WBITS=15.  This version of zlib does not support small or
 medium model with far allocation of big objects.
