nmd-article.cls

%%% Nathan M. Dunfield's personal LaTeX class %%%
%
% A document class which allows one to easily switch between the AMS,
% Geometry & Topology, and its own custom style (inspired by Hatcher's
% "Algebraic Topology").  In particular, a document that uses this
% style can easily be switched over to either "amsart" or "gtpart"
% with minimal modification.  See "template.tex" a minimal useage
% example.
%
% Main options: custom (default), gt, ams
%
% Font options:
%   * custom look: utopia (default), times, stix, lucida.
%   * ams look: computer modern (default), utopia, times, stix, lucida.
%   * gt look: times (default and only option).
%
% Font size options:
%
%  * custom: 12pt (default), 11pt.
%  * ams look: 9-12pt with 10pt the default.
%  * gt look: 11pt (default and only option).
%
% Additional options in the custom look:
%
%  * fullpage: PDF is full US letter sized.
%  * fatpage: wider textwidth.
%  * grant: suitable for NSF grants.
%
%  Formating commands:
%    \trimpages, \laptop, \printing
