{Neptune\Dash a proofing framework for \LaTeX\ authors} {Aravind Rajendran, Rishikesan\regularorprogramstring{~}{ }Nair\regularorprogramstring{~}{ }T\regularorprogramstring{~(presenter)}{*}, Rajagopal~C.V.} {In academic publishing, \LaTeX\ authors may be considered problem mongers since they insist on better typography, adherence to conventions (particularly in math equations), usage of their finely crafted \LaTeX\ sources for final output and other myriad benefits offered by \LaTeX. In recent times, galley proofs are provided to authors as editable sources rendered as a web page in \XML\ or \HTML\ format. Authors who have submitted their articles in \LaTeX\ format are seldom comfortable viewing and editing the output as a web page since math equations do not provide the original \LaTeX\ sources to edit, \TikZ\ graphics, \Xy-pic and commutative diagrams, \texttt{prooftree} math, and the like have been replaced with their respective graphics, thus precluding the opportunity to edit in case a mistake is found; source listing with packages like \texttt{listings} suffer a similar fate, the woes are many and much more. Hence, \LaTeX\ authors are not without cause when they complain of publishers' lack of academic and semantic sensibilities. Our program Neptune is an answer for all these problems, wherein a \LaTeX\ author can be provided with copy-edited \LaTeX\ sources and corresponding \PDF\ output in the final print format side by side with enough facilities to navigate between source and \PDF, a navigable list of track changes showing copy edits that can be accepted/\allowbreak rejected, a navigable list of author edits during the proofing session, comparison of pre- and post-proof \LaTeX\ sources side by side with ability to discard any edit, comparison of pre- and post-\PDF\ versions, navigable query lists, multiple sessions for proofing, standard editor features, etc. This presentation will show all these features with the help of a live demonstration.}
