%%  This file provides the asmeconf LaTeX class for formatting conference papers according to 
%%  ASME conference requirements as represented on ASME's conference web pages in 2024.
%%
%%  This file's version and date:
	\def\versionno{1.37}
	\def\versiondate{2024/02/06\space}
%%
%%  Author: John H. Lienhard, V
%%          Department of Mechanical Engineering
%%          Massachusetts Institute of Technology
%%          Cambridge, MA 02139-4307 USA
%%
%%  This LaTeX template was designed to approach the following aims:
%%
%%          1. Match ASME's current layout and font specifications
%%          2. With amseconf.bst, match ASME's reference formats including DOI & URL (replaces asmems4.bst)
%%          3. Provide hyperref compatibility for hyperlinks, pdf bookmarks, and metadata
%%          4. Set author names in either the traditional grid or the more recent inline style
%%          5. Support citations, footnotes, and bold face, sans serif math in section headings
%%			6. Provide line numbers for editing and review
%%			7. Support balancing length of columns on last page
%%			8. Provide copyright footer for federal employees and contractors
%%			9. Support the archival PDF/A standards 1b, 2b, 2u, 3b, and 3u
%%		   10. Enable various math and text features from the newtxmath and newtxtext packages
%%		   11. Support inclusion of passages in languages other than English
%%
%%  This class is compatible with either pdfLaTeX or LuaLaTeX. Fontspec will load automatically with LuaLaTeX,
%%  but the class does not support unicode-math. To use LuaLaTeX without fontspec, call the [nofontspec] option.
%%
%%	Use an up-to-date LaTeX distribution: for pdfLaTeX, TeX Live 2020 or later; for LuaLaTeX, TeX Live 2021 or later.
%%  A complete LaTeX installation is also recommended: asmeconf loads ~30 packages, in addition to LaTeX core packages.
%%	All packages required by the class are in TeXLive and CTAN (https://ctan.org/). 
%%
%%  Commands for entering conference headers and author names are specific to this class.
%%  See asmeconf-template.tex for details.
%%
%%  The class defines abstract (with keywords), abstract* (no keywords), and nomenclature environments. 
%%  The latter has an optional argument to control the space between the entries and the definitions.
