% The pandoc command line (see configure.py) can communicate variables to this
% LaTeX skelaton, by using the "-V varname=value" command line parameter, and
% there are also some builtin variables defined by other options. With such a
% variable, we can use "$varname$" for the value, and $if(varname)$...$endif$
% for conditional code when this varname is defined.
%
% For an example of a more complete LaTeX template covering more of pandoc's
% features, check out the example templates/default.latex in pandoc's
% installation, or pandoc.org/demo/mytemplate.tex on their site.
