I would like to install program foo using
emerge on a Gentoo system; so I simply use
emerge foo to install and portage selects the most current version of that software that's in its repository. If I know the version number and the naming covnention, I can do
emerge =foo.1.2 and use
eselect to chose what the currently inforce package is out of the installed ones, if the package supports it.
But what if I don't know the version number or naming convention and just want a list of what's versions of foo are available to me? I don't see an emerge option that does this and snooping around under
/usr/portage doesn't yield me anything.
Bonus: Is there anyway to find what locations
emerge polls to determine what packages are available? For example, many of the ebuilds on my systems are in nonstandard locations, but
emerge finds them anyway, so I'm attempting to determine how
emerge builds it's list of available software versions.
