Following a subtle suggestion at
http://news.povray.org/povray.general/thread/%3Cweb.5d9c84adcc983787ecc0fada0%40news.povray.org%3E/

I need to calculate the object width in the first run, and parse the output of
#debug stream to set the camera location in the main run.

I do this by a shell script in linux, but the output of povray command contains
lots of information (credit, rendering, etc).

How can I limit the output of the povray command to #debug stream?

however, I'd be tempted to write the information needed to a text file, from the
scene (ie using '#write').  that way you you can reduce the need for "parsing"
(or, at least, make the task easier).

I like jr's suggestion.

The way I do it is with parsing.  You can't really control the noise 
around you, so make your noise noticeable.
i.e.
#debug concat("[myData] ObjectWidth ", str(ObjectWidth,0,3), "\n")

Then you know any line beginning with [myData] is one you care about for 
this application and you can ignore everything else.
