I would consider this to be ultra cool.

{Rick considers offering to do this update and comes to his senses}

I would suggest that the best way to do this might be by building a sed script and then running a link checker if there is such a thing.

please read the commented notes below.

# directory.dat
#
# Rick Graham, BitFlash
# Nov., 2001
#
# This file describes the directory tree structure for the SVG 1.1 test suite
# this is a tab delimited file
# feilds are:
# section name, chapter or .section number, title
#
# Field 1, section name
# section names are 'chapter' and 'chapter-section'
# at the time of creation, chapter names were the same as the html names in the 1.0 spec.
# section names in the spec are too verbose to fit into the test file naming convention so they
# do not mirror the links in the spec.
# 
# Field 2, chapter or .section number
# chapters are numbered as integers, sections are preceded by a decimal to 
# differentiate them.
# The reason I did this was to avoid having a huge renumbering task in the event that
# there was a chapter added or deleted.
#
# Field 3, Title
# This is the title of the section as it appears in the spec.
