Wiki Tool With COW Semantics

[eatnumber1]

It'd be nice if there was a tool which read from the nethack wiki and automatically applied some patch to the article which we write before displaying the information to the user. For example, a command line tool could pull from the nethack wiki and our wiki, and apply modifications from our wiki to the information pulled from the nethack wiki. Alternatively, we could regularly scrape the nethack wiki and apply patches from our wiki, putting the result up as our project page.

Thoughts?
