# Script to tidy up the spec HTML files that are generated by xmlto. The
# following changes are made:
# 2. Create reverse links from chapter and section titles back to the TOC.
# 3. Tidy the ix01.html file - the actual index - by splitting long lines.
# 4. Insert links from the letter divisions to the top of the Index.
+# 5. Turn <div class="literallayout"><p> into <div class="literallayout"> and
+# a matching </p></div> into </div> to get rid of unwanted vertical white
+# space.
+# 6. Before each occurrence of </td> insert so that the table's cell
+# is a little bit wider than the text itself.
