Create pull request for t:slim support

[kentquirk]

@yrrebnarg -- you forked this repository and mentioned it in IRC -- but for us to take it (and to make it easier to look at your request) you should create a pull request.

Also, before we can take the pull request, you'll need to agree to our Contributors License Agreement. Details on how to do that are here.

Thank you!

I was going to wait until I had some of the parsing finished, but I suppose there is no harm in putting in an early pull request.

Please just note that it's not yet ready for merging.
