Not much of it, I'm afraid. We need to start writing something!

Within existing modules? Try copy and paste.

Jamie,

Have you checked Bio::Map modules. There are some Interface files and as
well as simple implementations for maps, markers and positions. I'd like
to think they are useful for this kind project.

Also, have a look at Bio::Assembly modules. They are under development 
but should represent nicely general assembly project.

Your project would be one kind of an assembly project so
Bio::Assembly::FPC would be an appropriate name space.

You need to have a copy from CVS to see the Bio::Assembly modules.
The bioperl website has instructions for anynomous access to start with.

Yours,

->isa(Bio::Assembly::ScaffoldI)? If not there should be a more general class.

Ranges and comparing them e.g. between clones and contigs is what
Bio::Coordinate modules are for. Bio::Coordinate::Collection is a class
you objects should be using. 

They are new stuff as well, so feel free to pester me about them and
about (lack of) documentation.
