A simple interface where the user provides a list of function names to be
ignored would be a good start.

Something like:

hpc markup prog.tix --destdir=report
--ignore=fail,error,impossible,undefined

It _could_ also be a good idea to have a way of ignoring literals. Flags
like --ignore-num-literals and --ignore-string-literals could treat all
such literals as covered or ignored.

Maybe I should put this as a feature request to the hpc maintainers.
I am wondering if they maintain an issue tracker or not.

The wiki pages for hpc aren't very helpful...
