emerge regen causes portage to generate all missing cache entries
for any ebuild in the portage tree, as well as regenerate the ones
marked as expired due to an eclass change or the ebuild itself
changing.

It's a forced caching, basically. 'emerge sync' does the same thing
but does it with an extreme difference in speed by using the cache
that's generated on gentoo's servers. A complete regeneration can
take upwards of two hours, depending on the speed of the machine.

I'm not entirely certain what you're doing but the only use for
this function for non-cvs users is for the generation of a metadata
cache. As Gentoo does this itself, it seems unlikely that this
really is going to benefit anything you're trying to accomplish,
unless you have a _very_ large set of ebuilds that you're
incorporating into a private rsync tree.
