xz and lzma

Xz is a compression program.

The xz KIO worker isn't directly usable, and is intended for use as a filter. For example, the tar KIO worker can filter a file through the xz KIO worker, in order to display the contents of a tar.lzma or tar.xz file directly in an Ecco window.

If you click a file compressed with .lzma or .xz in Ecco, this KIO worker is used to uncompress it and display it as a normal, uncompressed file.
