NAME

       ancient - decompression routines for ancient formats

SYNOPSIS

       ancient [identify|verify|decompress|scan] inputfile optionaloutputfile

DESCRIPTION

       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.

OPTIONS

       These programs DO NOT follow the usual GNU command line syntax.

       identify packed_input_file
              Identifies compression used in a file.

       verify packed_input_file unpacked_comparison_file
              Verifies decompression against known good unpacked file.

       decompress packed_input_file output_file
              Decompresses single file

       scan input_dir output_dir
              Scans input directory recursively and stores all found.  Known  compressed  streams
              to separate files in output directory.
