for people who work with projects that require specific versions of autoconf
and nothing else (like ==2.64), i've long left older versions in the tree so
people could downgrade on the fly. this isn't so bad as you can do:
emerge -bk ~autoconf-2.64
<use it>
emerge -bk autoconf
but i'm super lazy, so even this manual step is annoying. as such, i've added
USE=multislot support to autoconf (just like it is with binutils & gcc).
now you can install multiple versions in parallel and run:
WANT_AUTOCONF=2.64 autoconf
or more specifically:
autoconf-2.64
without affecting the default `autoconf`.
the default is, of course, unchanged.
