Ok, I've put together a small list of portage calls mostly unigue, but
many have variations of the basic call (not listed)repeated for
different info returned. A few lines of code I left in to make it more
clear, but should give an overall list of the portage function calls
used so far.


I will put together a list of functions that I created in portagelib to
add functionality directly related to portage.  Some of them are copies
of code chunks from lifted from gentoolkit.
