Lots of changes to get the paragraph marking to work, and not go into
an infinite recursion.
Start to rationalize markup of method signatures; not complete.
find_all_elements(): similar to getElementsByTagName(), but operates
on the not-quite-legal fragments we deal with here.
Simplifies several individual transforms.
fixup_sectionauthors(): Convert \sectionauthor items to <author> just
after the <section>'s <title>.
currently generated by the LaTeX and LaTeX2HTML processes is generated
here as well, making it more flexible in the SGML version.
Reduce the <args> element so that <optional> goes away; just use
square brackets to indicate what's optional. This makes it easier to
read than the LaTeX, and the processor can do any checking it needs to
in order to make sure it's legit. Possible shortcoming: DSSSL
processors may need more explicit markup. Can probably hack around it
for this case, but we'll see.
<moduleinfo> element based on various meta information, and
strip some cruftiness. This is more usable for information
extraction, and organizes the information more clearly.
cleanup_synopses(): Rewrite to use create_module_info(), so this
will work with multi-rooted "documents".
