ancient - decompression routines for ancient formats


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


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.


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