javascript remote diff/merge tool

There are certain computer tasks that I sometimes wonder if there is a better way of doing them. I mean computers are there to save time, not generate work. One such task is remote file diffs, especially on our webfarm. When deploying updates to our developer site there are often files flagged that were not supposed to have changed.

My colleague Nimish has created a tool that can do a remote diff and merge and display the results in your local file browser. Apart from some python server hooks the rest is written in javascript. What was always a clumsy and error prone task I can now do locally as follows

jsblend.py scp://user@server:/opt/lib/file.pm /opt/lib/file.pm

and see the comparison in a web page.
