%%  `aiaa-tc.cls' - A LaTeX class to create AIAA technical conference papers.
%%
%%  The basic approach is to load the LaTeX article class and various
%%  standard LaTeX packages, and then make modifications and extensions to
%%  conform to AIAA's guidelines.
%%
%%  To use, simply select this class file in your LaTeX document.  For example,
%%
%%    \documentclass{aiaa-tc}
%%
%%  Class options:
%%
%%   handcarry - used for hand carrying a paper to a 'loose papers'
%%               conference.  It adds the conference name to the
%%               top of the first page, paper number to the bottom
%%               of each page, and a copyright notice on the bottom
%%               of the first
%%
%%      submit - produces output typically required for journal submission,
%%               that is, 12pt font and 'double spacing'.
%%
%%     handout - Edward Tufte-style format: footnotes and citations become
%%               sidenotes, column width is reduced to give ~60 characters-
%%               per-line to improve readibility, ragged-right used
%%               for improved readibility, and less-obtrusive sectioning
%%               styles.
%%
%%               Note: you will need to move your bibliography section to
%%               the beginning of your document per instructions for the
%%               bibentry LaTeX package.
%%
%%  plus those accepted by the standard article class such as 'draft'.
%%
%%  Class-specific commands:
%%
%%   \thanksibid{} - Reuses \thanks footnote symbol from previous
%%                   author specified by position in \author command.
%%                   For example, `someone\thanksibid{2}' will reuse the
%%                   footnote symbol from the second author for 'someone'
%%                   without producing a repeated footnote at the bottom.
%%
%%   \AIAApapernumber{} - For use with 'handcarry' option.
%%    \AIAAconference{} - Ditto.
%%     \AIAAcopyright{} - Ditto.  Must be filled with one of the
%%                        various copyright types: \AIAAcopyrightA{year},
%%                        \AIAAcopyrightB{year}{holder}, \AIAAcopyrightC,
%%                        \AIAAcopyrightD{year}, or \AIAAcopyrightDAPL{year}.
%%
%%   \AIAAsubmitinfo{} - Footer information used by 'submit' option.
%%
%%  For support, further details, and a documented version of this class,
%%  please read the Users Manual, aiaa.pdf, and the templates that come
%%  with the AIAA LaTeX distribution.
%%
%%  Wish list:
%%
%%  o fine tune hyperref behavior, especially footnote behavior
%%
%%  o an \appendix command to switch section styles, counters, etc.
%%
%% o leave space for copyright notice so that handcarry option does
%%   not alter pagination.
