ComprLib Data Manipulation Library

Hosted at SourceForge (6453)

ComprLib is a C++ data compression library. Update 20040708: A CVS snapshot of ComprLib 2.0 from 2000-06-14 as well as ComprLib 1.0 (including WinCompr) is now available in a Zip archive. If you have any questions contact me. ComprLib is no longer actively maintained; if you came here looking for a portable, high- quality, maintained compression library, I recommend libbzip2 or zlib.
