XFH-handler is a DOS handler which uses xpkmaster.library to provide
transparent access to compressed files in a given directory or partition.
All compression/decompression is done automatically by the handler when files
are read or written. Compression is optional and may be switched at any time,
allowing for fine control over storage of data. The compression method may be
changed at will. Decompression is always automatic, you don't have to care
about which compressor was used to create the files.

This version of XFH is designed to work with Xpk, the data compression
standard. You will need Xpk to use XFH. Most users should receive XFH as part
of the Xpk distribution.
