/*
* pts_defl.h -- C header file ZIP compression ripped from linux-2.6.8.1
* by
[email protected] at Tue Jan 18 15:19:06 CET 2005
*
* This ZIP compression (ZIP == PostScript /FlateEncode compression filter
* (ZLIB RFC 1950)) routine has been ripped from the Linux kernel 2.6.8.1
* (directory lib/zlib_deflate), which has been ripped from ZLIB 1.1.3
*
* This is a minimal .h file, to avoid namespace pollution.
* See more in the beginning of pts_defl.c
* For documentation comments, see pts_defl.c
