the angle, to steal my own thunder, is that you can easily use
the pagenumber information that's contained in the o.c.r. files
to rename your .txt and .png files in a more-intelligent manner.

if the pagenumber in file "011.txt" says that it's pagenumber 7,
you'll rename "011.txt" and "011.png" to "007.txt" and "007.png".

easy as pie!
