This is a list of the major differences between
the acmtrans macros and the acmart macros.

===========================================================================

CHANGES TO ACMART CLASS

-----

acmart.cls is a LaTeX2e class that can be used
either in native mode or compatibility mode;
acmart.sty can be used in compatibility mode in
LaTeX2e.  acmtrans could not be used with LaTeX2e,
even in compatibility mode.

-----

Added preprint and faircopy options

-----

Modernized, cleaned up, and optimized the code for
memory use

-----

Updated copyright notices

-----

Moved \rm from \thesubsubsection and \theparagraph
to \@sect.  (This was preventing acmtrans from
working in compatibility mode under LaTeX2e.)

-----

Removed "height .004pt" from \footnoterule.  That
can't possibly be right.

-----

Changes in \maketitle:

-- suppressed floats at top of title page

-- put in warnings for cases where there is either
   no abstract or the abstract is put placed after
   the \maketitle

-- fixed bug that caused abstract to be dropped if
   there were no \category's

-- Fixed spacing between Catetories and General
   Terms and between General Terms and Keywords in
   case where terms or key words occupy more than
   one line

-----

abstract environment works properly if there are
blank lines after \begin{abstract}

-----

\category rewritten to properly handle case where
3rd argument or 2nd and 3rd arguments are empty
(but should probably also be fixed to detect cases
where, for example, 2nd argument is empty but 3rd
isn't.)

-----

Added \figfilename command for marking figures with
their associated file names in faircopy mode

-----

Fixed \nocaption so it works with any float, not
just figures.

-----

Shortened first page to make room for information
stripped in by ACM.

-----

Changed numbering of Appendix from

   APPENDIX A. Section one of appendix
   APPENDIX B. Section two of appendix

to

   APPENDIX

   A. Section one of appendix
   B. Section two of appendix

-----

Changed subsection numbers in appendix from "A1"
to "A.1"

-----

Enhanced \citeN and \shortciteN so that they can
be used to generate references of the form

    Polychronopoulos [1990, 1991]

when used as, e.g.,

    \citeN{Polychronopoulos90,Polychronopoulos91}

It's an error if the references don't have the
same author lists.

-----

Added $*$-variants to \cite macros to replace the
NP-forms.

-----

Changed \makecaption so it produces correct format
with a caption more than one line long.

===========================================================================

MAJOR CHANGES TO ACMTRANS BIBLIOGRAPHY STYLE

-----

Inserted quad space around years, i.e.,

    Knuth, D.~E.\quad 1984.\quad ...

-----

Modified InProceedings so that the address and
date of conference is surrounded by parentheses
and put after the title of the proceedings, e.g.,

    \emph{Proceedings of the Third Annual
    Symposium on Switching Circuit Theory and
    Logical Design} (Chicago, Illinois, 7--12 Oct.
    1962).

-----

Changed formatting of authors so that if there is
a "junior" part, it comes after the first initial
instead of before, e.g.,

    Archer, J. E., Jr.

instead of

    Archer, Jr., J. E.

-----

Removed crossref formatting so BibTeX will never
produces references that look like

    Calabi, L. and Riley, J.~A. 1962.  The algebra
    of Boolean formulas: Some criteria for
    minimality.  See \citeN{FOCS3}, pp. 33--47.

where FOCS3 refers to:

    American Institute of Electrical Engineers
    1962.  {\em Proceedings of the Third Annual
    Symposium on Switching Circuit Theory and
    Logical Design}, Chicago, Illinois. American
    Institute of Electrical Engineers.

(I assume this is not desirable, but can put it
back in if for some reason it is wanted.)

-----

Made sure there is always a period after the
authors, so you don't get something like

    Pingali, K. and Arvind 1985.

instead of 

    Pingali, K. and Arvind. 1985.

(Again, this is an assumption on my part, and can
be changed if necessary.)

-----

Removed parentheses from around "Ed." and "Eds."
abbreviations.

-----

TODO:

modify acmtrans.bst to produce output more in line
with what the ACM requests?
