# Takes a chapter as input and adds internal links and numbering to all
# of the H1, H2, H3, H4 and H5 sections.
#
# Every heading HTML tag (H1, H2 etc) is given an autogenerated name to link
# to. However, if the name is not an autogenerated name from a previous run,
# it will be kept. If it is autogenerated, it might change on subsequent runs
# of this program. Thus if you want to create links to one of the headings,
# then change the heading link name to something that does not look like an
# autogenerated link name.
