http://linuxfocus.org/English/March1998/article30.html

To use the pov utility as described in the article
you need to change the variable POVRAY in the script "pov"
to point to the povray installation directory.
E.g:
POVRAY=/usr/local/povray31g/povray31

afterwards you can use this pov script as follows:
./pov sample1 4 9 

The parameter passed to the script are:

     Source file is burbujas.pov 
     Size 6 = (400x300) 
     Quality 9 

pov version 2 requires that you have imagemagick installed. It need
the programs convert and animate from imagemagick.

pov version 1 uses just xv to display the images.
