A rough start for what could be a nicely polished Sublime Text bundle for Loom. I wanted to start from scratch instead of just duping some ActionScript syntax file. I'd also like to see a robust collection of snippets and build system commands.
Until Package Control is setup:
cd "~/Library/Application Support/Sublime Text 2/Packages/" # Or your platform's equivalent
git clone https://github.com/ambethia/Sublime-Loom.git Loom
There's lots to be done. Changes to the tmLanguage file are made through the JSON file via AAAPackageDev.
