zer has asked for the wisdom of the Perl Monks concerning the following question:

Good morning,

Is there anything available that I can compair two strings to determine how closely they match each other? I am thinking there should be a perl module for this but I can't seem to find any.

Alternately, I would likely program this myself. Perhaps there is an algorithm or some experience in the monestary that could point me in the right direction so I don't end up recreating the wheel.

I have text that was munged up by an application. I need to be able to crossreference that text with the original as the munged up text has changes i need to make to the original.

Thanks for all the help!
