[TIP] Export tox commands for non-toxable environments?

[Ned Batchelder]

I'm using tox to run tests on multiple Pythons for coverage.py.  But tox 
won't run on 2.3 or 2.4 (I know, ancient), which coverage.py still 
supports.  I'd like to be able to export the commands tox would run so 
that I can execute them manually in another environment.  Something like 
"tox --dry-run" would be perfect.  It would output "pip install REQ" for 
each requirement, and "CMD" for each command.  Does anything like this 
exist?  Am I missing some subtlety that makes this a silly request?

I can probably hack something together by parsing the tox.ini or the 
output of "tox --showconfig", but that seems like the wrong way to make 
it happen.

PS: Is "non-toxic" a better adjective to describe environments tox 
doesn't support? :)
