I'll be shepherding this patch, since it still needs a bit of work.

For example, there is no host package for google breakpad, so it does
not work for me as I do not have googlebreakpad install on my host.

Also, I now know why you need this eval in the script. I do not like it,
so I'll try to come up with an alternative solution. Still, I have one
question: do you expect that one would enter shell wildcards in the list
of files to "breakpadize"?

It's a bit late here, now, so I'll continue tomorrow evening (GMT+2).

Regards,
Yann E. MORIN.
