I'm going to marinate on this a bit, so any and all input and comment are
good.  Eventually, I'll write something up for the q-applets, in C. That
ought to be fun, I just hope my code does not get 'vaperized'..

There's a chicken-and-egg problem with storing the EAPI in a variable
within the ebuild whose EAPI you need to know to parse the ebuild that
contains the EAPI variable whose value you need before you can parse the
ebuild...

It's a little silly, but the simplest workaround for that was to make
the EAPI variable grepable. As a result, the actual regular expression
that an EAPI declaration must match is in the PMS:

For future reference, this would be a bit more efficient:

grep -r -l --include="*.ebuild" "EAPI=6" .

This way, grep only looks at the files you want to search anyway.
