I recently had to edit a LaTeX file which has had numerous maintainers in the last couple of years. The header contains a block of %TCIDATA tags:

%TCIDATA{Created=Thu Jul 15 15:10:55 1999}
%TCIDATA{LastRevised=Monday, October 02, 2006 18:14:51}
%TCIDATA{<META NAME="GraphicsSave" CONTENT="32">}
%TCIDATA{<META NAME="PrintViewPercent" CONTENT="100">}
%TCIDATA{Language=American English}

What do these tags do? Who parses them?

I googled tcidata and tcidata latex but found no meaningful results.

My google is more informative than yours:


Ths article presents a program that facilitates the creation of customized LATEX style files. The user provides a style specification and the style editor writes all the macros. Editing takes place in a graphical user interface composed of windows, menus, and dialog boxes. While the editor may be used in any LATEX environment, it is intended primarily for use with TCI Software Research's word processor Scientific Word.

Your lines are LaTeX comments. They seem to describe the history of the generated file (probably written when saved from Scientific Word many years ago). It's likely that nothing parses them.

+1 for the 'more informative google' :D – Count Zero Feb 4 '13 at 15:45
That program was an extremely cunning trick from the Devil to cause hatred to spill over the world, undoubtedly. – Mariano Suárez-Alvarez Feb 4 '13 at 18:55
Not only was your google more informative than mine. You were also much better at making sense of the result. Thanks! – severin Feb 5 '13 at 12:38
