Google Apps Script - How To Publish / Install A Container-Bound Script

I have a document container-bound script, that I would like to publish, I
would like to make it available to people in my google apps organization.
I know the script gallery is only available to spreadsheet apps, so how do
I publish it. Or, more specifically, currently the script is bound to one
document, how do I make it run on all documents? My user base is fairly
small, about 300 people, and I can have each one of them install it if
need be.
Thanks, Ari
