ancient - decompression routines for ancient formats

       This manual page documents briefly the ancient command.

       ancient  is  a collection of decompression routines for old formats popular in the Amiga, Atari computers
       and some other systems from 80's and 90's as well as some that are currently used which were  used  in  a
       some specific way in these old systems.
       For  simple usage both a simple command line application as well as a simple API to use the decompressors
       are provided. The compression algorithm is automatically detected in most cases, however there  are  some
       corner cases where it is not entirely reliable due to weaknesses in the old format used.
