Actually, this feature is already available, I believe, through the
:HERE directive in the configuration language.

This was something we added for the case that I found common, where
there would be a project directory tree, with all the required code in
subdirectories, and a master configuration file at the root.*

Have a look at that and see if it does what you want.


* In practice, we create these trees by checking a project out from svn.
We'd have all the required libraries, in stable versions, included as
svn externals.
