Text::Levenshtein is an implementation of the Levenshtein edit distance in Perl. A good point to start is: See also Text::WagnerFischer on CPAN for a configurable edit distance. PREREQUISITES This suite requires Perl 5; I tested it only under Perl 5.6. Text::Levenshtein does not use any nonstandard modules. INSTALLATION You install Text::Levenshtein by running these commands in the *nix environment: perl Makefile.PL make make test (optional) make install To install Text::Levenshtein in the Win32 environment, use nmake instead of make. nmake is available for free (in a self extracting executable): After download and inflate, put nmake.exe and nmake.err in c:\windows\command . DOCUMENTATION POD format documentation is included in Levenshtein.pm. POD is readable with the command: perldoc Text::Levenshtein AVAILABILITY The latest version of Text::Levenshtein is available from the CPAN COPYRIGHT Copyright 2002 Dree Mistrut This package is free software and is provided "as is" without express or implied warranty.
