%% This package was written by Joseph A. Smiga &lt;joseph.smiga@rochester.edu&gt;
%% Originally developed ca. 2018, this has been refined over the years.
%%
%% Some useful commands: (not up to date, see documentation)
%% Included are a set of commands to generate comments for a LaTeX file.
%%
%% This package requires the following standard packages: 
%%     ulem: for \sout
%%     xcolor: for coloring text.
%%     pdfcomment: if pdfcomment option is used
%%
%% Options are:
%%     arrows: add arrows pointing to edits in margins (in captions, a pair of arrows are added, instead).
%%     accept: accept all edits (arrows still appear).
%%     pdfcomments: write edits as pdf annotations (arrows still appear).
