vmprofshow --filter could use some explanation, and maybe be different

When asking vmprofshow --help you get this:

  --filter FILTER

that's not very helpful! I read the code:

vmprof-python/vmprof/show.py

Line 137 in ca0c4e0

if self.filter is None or funname.find(self.filter) != -1:

to find out what it does and it's not terribly useful of a filter. It won't let me target the path and that's what can separate my code from lib code. (Plus what's with "find" instead of "x in y"? :P )

I'm closing this for now. The commit will be release soon.
