where is gnc_module_system_init() called?

Check out src/scm/main.scm, in particular the function gnc:startup,
where it calls gnc:module-system-init (which is the g-wrapped
gnc_module_system_init() call).

Yes.  Right now the gnucash application is "defined" by main.scm.  It
loads all the gnc-modules (by name), and their dependencies.  However,
if main.scm does not know about a file/module, and it's not a
dependency of another file/module, there is no way (currently) to get
it loaded into the system.

main.scm :)
