Lhasa is a library for parsing LHA (.lzh) archives and a free replacement
for the Unix LHA tool.
Currently it is only possible to read from (i.e. decompress) archives;
generating (compressing) LHA archives may be an enhancement for future
versions. The aim is to be compatible with as many different variants
of the LHA file format as possible, including LArc (.lzs) and PMarc (.pma).
The command line tool aims to be interface-compatible with the non-free
Unix LHA tool (command line syntax and output), for backwards compatibility
with tools that expect particular output.
