Sort::Versions - a perl 5 module for sorting of revision (and similar) numbers All files in this package are Copyright (c) 1996, Kenneth J. Albanowski. All rights reserved. This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself. This module allows easy sorting (via comparisons) of mixed text and numeric strings, similar to the complex "version numbers" that many revision control packages and shared library systems use. For an explanation of the algorithm, it's easiest to look at these examples: 1.1 < 1.2 1.1a < 1.2 1.1 < 1.1.1 1.1 < 1.1a 1.1.a < 1.1a 1 < a a < b 1 < 2 (special handling for leading zeros) 0002 < 1 1.06 < 1.5 (a hyphen binds looser than a period) 1-1 < 1-2 1-2 < 1.2 To install, make sure you have perl 5.002 or higher, unpack, and say: perl Makefile.PL make make test If the tests are successful, say as root: make install And that's it. Further documentation is available in the Versions.pm file, which may be accessed via 'perldoc Sort::Versions' after installation.
