Ok this was a fairly interesting stat collection so i whiped up a python script to do this. I should invest some more time in lexing the right thing (now i lex lines but I should lex combination of lines split by ; instead), second thing is should allow for long strings too but hey its a hack. CHANGE the pathname!

Testing: not much testing, ran a few times on my
entire local project list. Some problems but
no critical issues.

About:
A simple script that will recursively iterate over
your folders and find all maya ascii files. Then try
to decipher the render range and calculate number of
frames, and tally this up.
Install Instructions:
place this text in a file named:
renderRangeFormAllMA.py
change the pathname and execute.
Usage:
change the pathname to point to your root

PS: this script has a security issue so dont run this on a webserver!
