digitalmars.D.learn - Compiler module import graph

Is there a tool to view module import graph?

The compiler verbose output shows that the module is 
imported/parsed but not why. I wan't to avoid unnecessary imports 
to speed up compile times or avoid issues if the module contents 
are not fully compatible with the current compile target being in 
development.

`dmd -deps` shows what imports what.

Be aware that there is a bug where DMD misses some edges in the graph:

For some reason the only output I get is 'interface function ... 
is not implemented' errors if I run this switch.

Ok, I was stupid forget the -m64 switch and had a size_t/ulong 
bug in an interface. Thanks.
