/*
 * This file is derived from various .h and .c files from the zlib-0.95
 * distribution by Jean-loup Gailly and Mark Adler, with some additions
 * by Paul Mackerras to aid in implementing Deflate compression and
 * decompression for PPP packets.  See zlib.h for conditions of

 * - changed functions not used outside this file to "local"
 * - added minCompression parameter to deflateInit2
 * - added Z_PACKET_FLUSH (see zlib.h for details)
 * - added inflateIncomp
