New script update_metadata to do a global update of both repos.
Add support to update_ebuilds to do incremental updates when just
pulling new ebuilds into portage-stable.
Anonymous CVS is too unreliable (or I keep getting blocked, who knows)
so switch the default remote source to the Gentoo rsync mirrors which is
probably what I should have done in the first place. :)
The big here document in the middle of a if statement confuses the code
layout some and I put the git commit outside of the else clause instead
of inside. Ooops. The joy of shell.
Meant to add this last week... It can either pull from Gentoo CVS or a
local directory (in case you rsynced the whole portage tree). Just name
a package by pkg-cat/name and it will update portage-stable.
