In  this  text the word archive is used to indicated a group of files, that
are  stored in one big file, possibly also containing the file-structure of
the original (directories) and maybe using compression to store the files.

Archives are mainly used to move large amounts of data from one computer to
another  (via  disk/modem/ftp/...).  Archives are also an easy way to store
that data.

The ARCHandler currently only supports  lha-archives.
