Snakefood

sfood -fuq package.py | sfood-target-files 

will list the dependencies.

`-f` tells sfood to follow dependencies recursively
`-u` tells sfood to ignore unused imports
`-q` tells sfood to be quiet about debugging information

To filter out modules from the standard library, you could use

sfood -fuq package.py | sfood-filter-stdlib | sfood-target-files 

As you've already noted, if there are other directories you'd like ignored, you can also use the sfood -I flag.
