And I'd like to know what made you to use multiple requirements.txt files, and their combination:
from catkin_virtualenv.
What motivated me to use multiple requirements files was the idea that you could have:
- package A implement library code that depends on external library B
- package C on package A, and inherit package A's requirement of library B transparently
I agree, the current implementation is fairly limited. It would certainly be possible to add support for other combination of constraints here.
- The combinatorial explosion would probably require taking a different approach than currently used
- A cleaner way would probably be to rely on the ability of requirements files to recursively include requirements files, letting pip/setuptools handle the messy resolution.

That was fairly easy, and I got to remove a bunch of code! #15
EDIT: closing the associated PR, not a good strategy. A better requirement-constraint-merging strategy should be implemented in catkin_virtualenv, unless pip changes the way it works with duplicated requirements.
