Thanks for the tip regarding Spirit, I was indeed unaware of it.

However, it's unlikely I would have used that library in this case,
for the same reason I opted to avoid boost:regex in this particular
module.  It struck me as unreasonable to pull in some hefty, non-
standard dependencies just for this one parsing function.

I do indeed use higher-level tools (like boost:regex) in other
contexts.
