How to add attachment type?

[XTF]

Hi,

What is the proper way to add an attachment type?
At the moment I insert it manually into the table, but then the cache of types needs to be rebuild manually (for example by 'editing' the type in ACP and changing nothing.
How can I do this automatically?

Hmm, I guess I should've said that I wanted to do it from a script.

I can execute the SQL queries myself, but vB appears to cache that table and I've no idea how to flush that cache.
Anybody?

You will need to rebuild the datastore cache.

You will need to rebuild the datastore cache.
Thanks. What's the function to call or where is that documented?
