Hi Vladimir,

Good question! I don't see any, either. That's a surprising oversight
AFAICT.
It looks like a simple Jam modification to set the bound path of each
scanned header into a target-specific variable (e.g. BINDING) might do the
trick.

Sounds like you don't have FTJam. SUBST is a built-in rule in FTJam.
