[OpenSCAD] Hooks and grooves?

Hello, algorithmically inclined CAD people,

I find myself in need of a hook-and-groove system (to put a bottom or a
lid on a box). The problem is that the edge may (a) have less than 90°
(think "base of a pyramid") and (b) may need to be inset by some amount
(think "heavily mitered edges").

Is there code out there which does that? While I'm no stranger to 3-D
geometry math, re-inventing the wheel isn't my favorite pastime.
