Well, using $directory makes the feature auto-documented and very easy
to read even without the reference documentation handy. It's also a very
known way to setup things in .ini files.

Now, what other parameters would you possibly use that way, other than
$directory? I can see a use for $default_version, but that's about it.

Would you rather add support for $default_version in the patch, for all
of the parameters just in case, for a different set of control
parameters, or rename the $directory macro?
My vote goes for adding $default_version only.
