Quoting Tudor Girba <girba(a)iam.unibe.ch>:
I recently had in my image complete FAMIX models from 18 versions of
ArgoUML, each version having over 1000 classes. This resulted in a 500
mb VW image and Moose worked just fine.
I've 20 versions of a c++ project growing from 7 MByte to 13 Myte
in (at the end) 982 .cpp and .h files. 200MByte in total.
What do you mean by file dependencies?
That's just counting the #include's.
