About LZMA I should add that when using higher (actually the default) compression rate, compression is much better than bzip2 but takes more time/memory. Decompression however, which is what really matters in a packaging format, is kept fast and lightweight. > The > downside is that LZMA is not supported by libarchive, and won't be > supported officially either, because libarchive is BSD licensed and LZMA > is GPL licensed. Can't this problem be circumvented by spawning the lzma command line utility, and piping all data to it? I understand that this perhaps negates the purpose of libarchive, but the overhead should be small. Thanks, Dimitris
