I've recently begun learning Erlang, and in the process made some updates to the Erlang bundle that might be useful to others. I've created an AppleScript that can perform basic remote control of a Terminal window running an Erlang shell -- enough to compile a source file at least.
There's a short screencast and download information on my blog: http://imbriaco.com/braindump/articles/first-post-erlang-and-textmate/
If the original author of the Erlang bundle reads this, I'd love to contribute this back to the official bundle. Feel free to contact me off list.
