{\TeX\ and copyediting} {SK Venkatesan and CV Rajagopal} {Copyediting of a manuscript involves bringing consistency at many levels, with many kinds of local and non-local changes. The \LaTeX{} macros of the proposed \textsf{copyediting} package offer an excellent way to create a markup that can string together all the types of changes that are made by a copyeditor in a consistent way. The English language also has certain localization requirements that could be handled through language switches in the spirit of Babel package. Localization can be achieved through macros such as \cs{vara\char`\{color\char`\}} that take care of variant spellings. We also propose further a family of macros for other copyediting requirements such as parenthetical commas, serial commas, Latin abbreviations, first-secondly-thirdly, \dots{} This copyediting package will simplify the task of copyediting and bring a higher level of quality to the final output.}
