Hey Campbell,

First, I'd like I'm not too keen on the format you chose
for specifying the frame number, i.e., "c:\renders\render_#.png".
That I would do instead is use a C format code such as
"c:\renders\render_%06d.png" (in this particular example, frame
numbers are zero padded and six digits long), so that there is
more flexibility in numbering frames.

Regarding the commandline, and order of args, etc., this came up
a bit quite a while ago when I was planning to pass args to
python through the commandline. The main point is that the
order of args is important so that you can treat batch rendering
as a sequence of actions on various files. Here are the relevant
emails:
