You probably don't need anything but sys (to parse the command options) 
and os (maybe).

open the file
     for eachline
         if one of the header lines, continue
         separate out the part you want
         print it, formatted as you like

Then just run the script with its stdout redirected, and you've got your 
new file

The details depend on what your experience with Python is, and what 
version of Python you're running.
