Description
I propose a standard LZMA2 (XZ) filter implementation for the Iostreams library.
LZMA2 provides much better compression than gz and bzip2. XZ is the default package format in Slackware GNU/Linux. 7-Zip, the most popular file compressor for Windows also uses LZMA2.
The source code of liblzma is found here.
A sample implementation of a Boost Iostream filter for lzma can be found in the fusecompress source.
I think it would be a big advantage because XZ is an upcoming file format which is used more and more in areas and by applications where saving bandwidth, memory or physical storage is important.
