This package is a UNIX port of the Amiga XPK library.

The XPK system consists of a master library (libxpkmaster.so) and several
(un)packer sub-libraries (libxpkXXXX.so). Application programs only use the
master library directly: the master library takes care of loading and using
the sub-libraries. Each sub-library implements one type of compression.

There are different libraries for different types of data. When unpacking the
applications do not need to know which library was used to pack the data -
the appropriate library needs to be installed.
