Package xz
This Go language package will enable reading and writing of xz-compressed files and streams. The complete package will be written in Go and will not use any existing C library.
The package is currently under development. Don't expect the code to work for you or the APIs to be stable.
Status
Package xz/lzma has now working support for "classic" lzma files. A lzmago binary supporting the typical flags for a UNIX compression command is provided.
To test it call the following command.
$ lzmago bigfile
After some time a much smaller file bigfile.lzma will replace bigfile. To decompress it use the following command.
$ lzmago -d bigfile.lzma
Be warned at this time the code cannot compete with the lzma binary from the xz tools. The algorithms in those tools have been developed over a long time and are highly optimized. But the lzmago tool happily decompresses files generated by lzma and lzma has no problems with files created by lzmago.

Overview ¶
Package xz allows the compression and decompression of xz files.
There is no functionality here, because I'm currently working on the components required to support parsing the xz format. Check https://github.com/ulikunitz/xz/blob/master/README.md for the current status.
