Changes upto v0.5.1

Navigation Panel

The navigation panel is now fully configurable and much better looking.

Automatic Signatures

The signatures at the bottom of each page are now constructed using nslookup (Thanks to Alberto Accomazzi <alberto@cfa.harvard.edu>)

Numerous fixes including...

• ``dead'' next_page buttons when the -split option was used, and
• internal LaTeX2HTML markers appearing in section titles.
