%%  This file provides the asmejour class for formatting papers in a layout similar to 
%%  ASME Journal papers.
%%
%%  The asmejour.cls file should be used with the files asmejour.bst (for citations) and asmejour-template.tex.
%%
%%
%%  This file is version 1.09 dated 2019/11/07.

%%          Massachusetts Institute of Technology
%%          Cambridge, MA 02139-4307 USA
%%
%%  This class is compatible with either pdfLaTeX or LuaLaTeX. The class calls a number of packages,
%%  many of which are part of the standard LaTeX distribution, and all of which are in TeXLive and
%%  CTAN (https://ctan.org/). 
%%
%%  The Times/Helvetica style fonts are from Michael Sharpe's excellent newtxtext and newtxmath packages.
%%  This class is not designed for unicode-math or fontspec.
%%
%%  Options for the class are described on lines 63-173. 
%%
%%  The class defines an environment for nomenclature. LaTeX must be run twice to align those columns.
%% 
%%  The title block is set by a specific group of commands which are described in the asmejour-template.tex file.
%% 
%%  The \section[]{} command's optional argument is changed to provide pdf bookmarks when necessary.
