About to implement preprocess

[jpillora]

Just curious if it will get in. Are you accepting PRs?

[flosse]

What about a simple quick implementation? (see #49)

[ljharb]

I'm not sure what you mean by "it"; the PR needs the "allow edits" box checked, but I'll close this.

Nearly a 10 year old PR :O no recollection of opening this lol
