[TIP] merging requirements.txt with specified deps

[Antony Seedhouse]

I have not seen the benefit of using (or being forced to use) setup.py for
this or many projects: as you said, requirements.txt contains the freeze of
the deployment configuration, which as a deployed application not a library
is all that is needed?

If tox supports "merging" dependencies from setup.py & depends, and tox has
added support for requirements.txt, then it would make sense for them to be
some way to use both ways?

I simply want to use tox to be able to easily test the project against
multiple versions of dependencies, and avoid having to keep multiple places
up to date, or having to create n number of files where n is the number of
dependencies that can change :)


Best regards,
Antony
