+# 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.
