I want to code it in my fork and I will pull it back to rerun.

I think that it's ready. For testing you can download my fork and run the rake install command for having my version of rerun locally.

For me it's working like a charm.

Hey @RaVbaker - you may already know about this feature, but if you put something like:

This closes issue #33

... somewhere in the description of your pull request #40 then github will automatically close this issue if/when the pull request gets merged into master.

edit: sorry, I just noticed that you already included it in the commit message, which effectively achieves the same thing... ignore me 😄
