The names of the original files must have one of the following The names of the original files must have one of the following
extensions: extensions:
'.bz2', '.gz', and '.xz' are recompressed to '.lz'. '.bz2', '.gz', or '.xz', which are recompressed to '.lz';

Keeping the combined extensions ('.tgz' -> '.tlz') may be useful when Keeping the combined extensions ('.tgz' -> '.tlz') may be useful when
