[sword-svn] r343 - trunk/versification

Author: greg.hellings

New Revision: 343

Added:
   trunk/versification/v11n_check.py
Log:
Added a script which compared word frequencies between two modules
and reports verses which differ greatly from the mean word ratio.

Can be useful for helping to check that a module is in the correct
versification scheme and that it does not have too many words
crammed into the last verse in a chapter.
