Identify the formats of regina data files
Usage
regfiletype file ...
regfiletype {-v,
--version | -?,
--help}
Overview
This utility determines which file format a given Regina data file is in. You may pass multiple files on the command line; the format of each file will be written to standard output.
Only Regina's modern XML-based file formats are recognised (both compressed and uncompressed). In its very early years, Regina used an impenetrable and undocumented binary format; this was replaced with XML in 2002 (Regina 3.0), and support for this format was removed completely in 2013 (Regina 4.94). If you still need to recognise and/or read files in this ancient binary format, you will need to download Regina 4.93.
