# This script is called by the script depend.py to create a "master table of contents"
# for a set of LyX docs.
# It does so by going through the files and printing out all of the
# chapter, section, and sub(sub)section headings out. (It numbers the
# sections sequentially; hopefully noone's using Section* in the docs.)
# It is called using this syntax:
# depend.py doc_toc.py SetOfDocuments
# where SetOfDocuments is a set of documents
