I have two scalars containing two similiar sequences of English text (1+ paragraphs). One is a draft, one contains minor edits (sentence added, sentance removed, spelling corrections, etc). I want to get a quick English readable version of the differences between them (eg "Sentance 'The quick brown fox jumped.' added at line 34. Sentance 'The lazy cat ran.' removed at line 37. 'and further more' changed to 'and, furthermore' at line 50, etc). I was about to embark on writing a module to do it, but it occurs to me that one might already be on CPAN. Any ideas?
