As most of you probably know I'm going to work as mentor for Maximilian
during the summer, but most (if not all) of the technical discussion is
going to take place here on this list, and we'd greatly appreciate any
comments and feedback you have.

I'd recommend using a period, like
Do we have any module naming conventions?

You can copy the makefile from another module, like d.path, and modify
it to suit your needs, or copy the example Makefile, and modify that.
The makefiles are set up so that they compile all C files into a module.

I don't really see it being used anywhere else, so I'd just start by
putting it in a file of it's own, and developing it separately from the
module, so it can be integrated into the Directed Graph Library later,
if we choose to do that. Anybody else have views on this?

I only have the CVS version checked out. I know others have multiple
versions installed for testing, but I'd say it should be enough for you
to have only the CVS copy checked out. Spearfish data could be used, or
then you can make your own, or perhaps someone has a suitable data set,
like showing buildings in an area?

Welcome, welcome. I think it will be an interesting summer (of code ;))
