I am going to give this a prod. There is a slightly updated version on
the forums (http://bbs.archlinux.org/viewtopic.php?pid=393865).
The only question I have for everyone is what is the best way to deal
with provides? e.g. Currently:
> ./pactree glibc
+--bash provides sh
But there is the possibility that multiple installed packages provide
something E.g. there are multiple packages that provide imap-server
that don't (all) conflict:
courier-mta/PKGBUILD:provides=('smtp-server' 'imap-server' 'pop3-server'
So what is the best approach here? If possible I think that continuing
down the dependency tree if we find one installed provider is good but
we should just list the providers if more than one.
