gEDA: Module Names from Icarus Code Generator

[Tom Hawkins <tom-at-NOSPAMconfluent_dot_org>]

I'm having quite a bit of success writing a back-end for Icarus.  After 
I got used to it, I realized the API is very well thought out.

Quick question: Given an ivl_scope_t, is there a way to determine what 
produced the scope (module, function, task, or named block) and to get 
the name of it, if it is a module?

Also, is there a definition of the LPMs anywhere?  They seem to be 
different than EDIF LPM.
