The home page of XZ Embedded is at <http://tukaani.org/xz/embedded.html>, where you can find the latest version and also information about using the code outside the Linux kernel. The xz_dec_test module is for testing xz_dec. xz_dec_test is not useful unless you are hacking the XZ decompressor. scripts/xz_wrap.sh is a wrapper for the xz command line tool found from XZ Utils. Since the XZ Embedded supports only streams with no integrity check or CRC32, make sure that you don't use some other integrity check type when encoding files that are supposed to be decoded by the kernel.

The presets in XZ Utils may not be optimal when creating files for the kernel, so don't hesitate to use custom settings. E.g. Branch/Call/Jump (BCJ) filters improve compression ratio of executable data. Double checking the integrity would probably be waste of CPU cycles.
