  • f63e26aee6 v1.03 prerelease - Full Linux port of crnlib/crunch, in progress - still more testing to do, and some cmd line options (such as -timestamp) don't work under linux yet, but the core stuff (compression/decompression/transcoding) should work fine and performance under Linux is comparable to Windows. The 3 examples haven't been ported yet. richgel99@gmail.com 2012-04-26 07:14:21 +00:00
