Rewriting make-docfile.c in Lisp?

[sbaugh]

I was recently trawling through make-docfile.c and wondered:

Couldn't this be written in Lisp?

It seems like this complex parsing code would be much simpler in Lisp,
and there's no reason the make-docfile step couldn't run after Emacs is
built.  It would be a fair bit of work, but I think the resulting
make-docfile.el would be much smaller and easier to understand.

I'm not about to go do it, but it would be a good self-contained
project, I think, so maybe a good addition to TODO?

Does anyone have any objections or reasons why this shouldn't be done?
