+Cactus Code Thorn zlib
+Author(s)    : Erik Schnetter
+Maintainer(s): Cactus team
+Licence      : ?
+--------------------------------------------------------------------------
+
+1. Purpose
+
+Distribute the zlib library; see <http://www.zlib.net/>
+
+
+
+From the web site:
+
+A Massively Spiffy Yet Delicately Unobtrusive Compression Library
+(Also Free, Not to Mention Unencumbered by Patents)
+
+zlib is designed to be a free, general-purpose, legally unencumbered
+-- that is, not covered by any patents -- lossless data-compression
+library for use on virtually any computer hardware and operating
+system. The zlib data format is itself portable across platforms.
+Unlike the LZW compression method used in Unix compress(1) and in the
+GIF image format, the compression method currently used in zlib
+essentially never expands the data. (LZW can double or triple the file
+size in extreme cases.) zlib's memory footprint is also independent of
+the input data and can be reduced, if necessary, at some cost in
+compression. A more precise, technical discussion of both points is
+available on another page.
