Revision 13449 (by tjaden, 2010/07/10 02:01:49) Improve web site styling, reducing use of tables for layout.

This also required a slight change to the way we process pages.
Previously we concatenated the header, content and footer files together
and ran once them through Pandoc, but that messes up some element
nesting as Pandoc introduces a new div for each header, without any way
to explicitly close it. Thus our footer divs would appear within the
div of the last content header. Now we run the header and footer
through Pandoc first, then prepend and append the generated HTML when
processing the content.

Rename inc.* to INC.*. Combine inc.a.header and inc.a.sidebar into
one file.
