It would be nice to have a command line switch to decide, whether the output file will be overwritten or not. Currently the output file is completely overwritten each time. This behavior has a drawback, espceially if i try to get all dependencies of a multi module project. The output file is overwritten for each module and so I get at the end the dependency tree of the last module.
For this whish i have prepared a little patch. I'll be very happy, if you accept my commitment.
P.S.: Sorry for my bad english. :/
P.S.2: I'm not very sure, if this issue is a "feature" or "wish" , please forgive me if i'm wrong.
