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
