 
  #asmejour: A template for ASME journal papers#
 
  Version 1.26 dated 2025/04/18.

  ####Overview####
  This class provides a template to format preprints in the style of journal papers published by the American Society of Mechanical Engineers. 
  The layout and reference formats follow the style of published papers in 2025.
  
  This work is not a publication of ASME.

 Files in this distribution are:

  ```   README.md              --  this file
      asmejour.cls           --  the class file
      asmejour.bst           --  bibtex style for ASME journal references
      asmejour-template.tex  --  a latex template/example for this class
      asmejour-template.pdf  --  documentation/sample paper
      asmejour-sample.bib    --  a sample bibliography file
      *
      sample-figure-1.pdf, 
      sample-figure-2a.pdf, 
      sample-figure-2b.pdf   -- figures for the example template
      /asmewide_example      -- directory includes asmewide.sty and examples of wide equations```	

  The .tex and .cls files are commented and should be self-explanatory.

  
  This template was designed to approach the following aims:

 - closely approximate ASME's fonts and layout, including author/title/abstract design

 - match ASME's current reference formats, including hyperlinked DOI and URL (replaces asmems4.bst)

 - support hyperlinks to figures, tables, equations, references, and external URLs

 - support pdf bookmarks and metadata

 - provide line numbers for editing and review

 - support balancing of columns on last page

 - support PDF/A (archival) standards if desired

 - support copyright notices for federal employees and contractors

 - support bold-face math and citations in section headings and captions

 - enable various math and text features with newtxmath, newtxtext, and inconsolata packages

 - enable passages in other languages, e.g., for a translation of the abstract or a quotation

 ####Change log####

v1.26 (2025/04/18)
 - Disable loading of exscale package by extarticle.cls (was causing spurious formula tag in section headings)
 - Correct order of setting the lsmgreek and fsmgreek symbol fonts
 - Move \\allowdisplaybreaks out of .cls and into .tex file, to allow user to control

 - Other minor changes in code and documentation

v1.25 (2025/04/07)
 - Add support for unicode-math, using fonts from TeX Live. LuaLaTeX now loads unicode-math by default.
 - Drop these packages: titlesec, enumitem, ifthen, iftex, totcount, hyperxmp, inputenc, bookmark, glyphtounicode 
 - Move hologo package loading from .cls file to .tex file
 - Drop \[mathalfa\] class option. User can instead load mathalpha in the preamble when using pdfTeX
 - Drop legacy PDF/A options \[pdf-a, pdfaconformance, pdfapart\]. Use \\DocumentMetadata instead
 - Select larger small caps from newtxtext by default, drop \[largesc\] option
 - Switch to LaTeX's native keyvalue mechanism; load kvoptions package only for backward compatibility
 - Change vertical skip adjustment on multline environment from 7pt to 10pt (= \\jot in this class)

 - Add pages and chapter to @book{.. entry in asmejour.bst; use pages= rather than eid= in sample .bib

 - Construct \\@author token list for consistency with standard classes
 - Revise documentation
 - v1.25 is PDF/UA-2 compliant if: \[captionpatch\] option is used; subcaptions are not used; figures are compliant; and \[nolists\] option is called or \\ref\* is used in optional argument of captions. Validation: Arlington model and demo.vera.org.
