[LRUG] Diffing Strings

[Eugene Bolshakov]

Hi Andy,

I came across an article a couple of weeks ago

http://phpcamp.net/toolbar/real-time-collaborative-editing-with-web-sockets-nodejs-redis

which mentions this tool

http://code.google.com/p/google-diff-match-patch/

It's not available in Ruby, but the list of public users is quite
impressive.

Eugene
