PivotalHook.post

Install this file into .git/hooks/post-commit and chmod 755 .git/hooks/post-commit

You may need to modify how the remote-url is getting generated - mine is set up as origin (see line 16)

Don't forget to add your PT_API_KEY (line 7)

Sample output once a comment is posted:

Awesome!

It looks like PIVOTAL_TRACKER on Line 7 isn't used... @syncrou?

@chrisarcand - Just realized that myself -Thanks! - Pulled it out and updated the comments.
