% Optional packages:
%
% If processing of these documents fails at your TeX installation,
% these may be commented out (independently) to make things work.
% These are both supplied with the current version of the teTeX
% distribution.
%
% The "fancyhdr" package makes nicer page footers reasonable to
% implement, and is used to put the chapter and section information in 
% the footers.
%
\RequirePackage{fancyhdr}\typeout{Using fancier footers than usual.}


% Required packages:
%
% The "fncychap" package is used to get the nice chapter headers.  The
% .sty file is distributed with Python, so you should not need to disable
% it.  You'd also end up with a mixed page style; uglier than stock LaTeX!
%
\RequirePackage[Bjarne]{fncychap}\typeout{Using fancy chapter headings.}
% Do horizontal rules it this way to match:
\newcommand{\py@doHorizontalRule}{\mghrulefill{\RW}}

% This gives us all the Python-specific markup that we really want.
% This should come last.  Do not change this.
