Because you might want to check that foo is installed from within foo, or you might want to check that foo-2 is installed from within foo-2, or you might want to check something subtly different -- and that's before we start thinking about slots. It's not really a bool thing, so has_version is the simplest way for people who need to detect a particular thing to detect it. -- Ciaran McCreesh signature.asc Description: PGP signature

If they absolutely totally need to detect that, then yes. Generally pkg_info should just try to display as much useful information as it can, though. In particular, it shouldn't do things like if we're installed, don't display this information, since people might be having trouble with a reinstall. -- Ciaran McCreesh signature.asc Description: PGP signature
