Text::LevenshteinXS is an XS implementation of the Levenshtein edit distance in Perl. A good point to start is: See also Text::Levenshtein on CPAN for a pure Perl version of this module.

INSTALLATION You install Text::LevenshteinXS by running these commands in the *nix environment: perl Makefile.PL make make test (optional) make install To install Text::LevenshteinXS 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 .
