My understanding is this:

1. For each file passed, use supplied module name
2. If an import is unknown look at each of the directories passed via -I 
and find it based upon a/b/c.d for module a.b.c;
3. For each file passed, if an import is unknown try to guess based upon 
paths

Of course rdmd adds another level of behavior on top and is mostly based 
upon the third one.

If in doubt, try using dub. It can show you all this without looking at 
code ;)
