The point is, it's an extension to a python based tool, written in perl,
using pipes for communication, and losing any advantages of integrating
with the tool it's extending.
I doubt you'd want to see system() to be used to subsequently extend the
perl tool.
I think it's just sad to see the documentation system slowly drift
further away from the ideals we had, and towards the old ways we worked
so hard to fix.

Please at least use fair and sensible comparisons. If you want to make
the extension usable standalone on the command-line, bypassing Sphinx,
you can do that. No need to factor in Sphinx to your comparisons.
