This directory contains examples of the use of zlib and other relevant
programs and documentation.

enough.c
 calculation and justification of ENOUGH parameter in inftrees.h
 - calculates the maximum table space used in inflate tree
 construction over all possible Huffman codes

fitblk.c
 compress just enough input to nearly fill a requested output size
 - zlib isn't designed to do this, but fitblk does it anyway

gun.c
 uncompress a gzip file
 - illustrates the use of inflateBack() for high speed file-to-file
 decompression using call-back functions
 - is approximately twice as fast as gzip -d
 - also provides Unix uncompress functionality, again twice as fast

gzappend.c
 append to a gzip file
 - illustrates the use of the Z_BLOCK flush parameter for inflate()
 - illustrates the use of deflatePrime() to start at any bit

gzjoin.c
 join gzip files without recalculating the crc or recompressing
 - illustrates the use of the Z_BLOCK flush parameter for inflate()
 - illustrates the use of crc32_combine()

gzlog.c
gzlog.h
 efficiently and robustly maintain a message log file in gzip format
 - illustrates use of raw deflate, Z_PARTIAL_FLUSH, deflatePrime(),
 and deflateSetDictionary()
 - illustrates use of a gzip header extra field

zlib_how.html
 painfully comprehensive description of zpipe.c (see below)
 - describes in excruciating detail the use of deflate() and inflate()

zpipe.c
 reads and writes zlib streams from stdin to stdout
 - illustrates the proper use of deflate() and inflate()
 - deeply commented in zlib_how.html (see above)

zran.c
 index a zlib or gzip stream and randomly access it
 - illustrates the use of Z_BLOCK, inflatePrime(), and
 inflateSetDictionary() to provide random access
