7534,Iostreams filter for LZMA2 (XZ),spixxi,Jonathan Turkanis,"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 [http://tukaani.org/xz/ here].

A sample implementation of a Boost Iostream filter for lzma can be found in the [http://fusecompress.sourcearchive.com/documentation/2.6.git913897f4-1ubuntu1/files.html 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.",Feature Requests,new,To Be Determined,iostreams,Boost 1.52.0,Optimization,,,marius.spix@… liling@…
