The build process tests for the presence + of a useable installation of bzip2. If none is found, the internal + source code is used. If bzip2 is not installed in a standard + location, the correct location can be specified either with + environment variables or with a config file. + +Bug fixes: +========== + +* previous versions were either not functional or not interoperable + with bzip2 when dealing with files larger than the internal buffer + size (100k to 900k). The 2.x series uses the logical eof rollover + method described in the bzip2 docs. + +What is Bzip2 ? +=============== + +Bzip2 is a portable lossless data compression library written in ANSI +C. It offers pretty fast compression and fast decompression. Bzip2 +has very good results, if you want to compress ASCII Documents. + +Bzip2 is probably not great for streaming compression. It fills it's +internal buffer, which depending of parameters is between 100k and +900k in size, before it outputs ANY compressed data. It works best +compressing an entire document. + +Streaming decompression on the other hand, gives a steady torrent of +bytes. |
