-%% M. Doob's "Gentle Introduction to TeX" (Updated 01/04/90)
-%% translated into Modern Greek by Dimitrios Filippou (including
-%% an extra chapter on typesetting Greek texts by TeX).
-%%
-%% Version: 1.000 (11 jan 2001)
-%%
-%% A NOTE TO THE CODE READER
-%%
-%% Thanks for your interest in the Modern Greek translation of Michael
-%% Doob's "A Gentle Introduction to TeX". Any comments on this manual
-%% would be appreciated. These may be typesetting, Greek, English or TeX
-%% criticisms.
-%%
-%% This file is a complete TeX input file, but, in order to run it
-%% smoothly, you will need to have the KD* Greek fonts (that is
-%% Dryllerakis' GreeKTeX fonts version 3.1, or, better, version 4.0a)
-%% installed on your system. If you don't have these fonts, you may get
-%% them by ftp from any CTAN site or from "laotzu.doc.ic.ac.uk". In
-%% case you have KD* fonts on your system, just run this file through TeX
-%% and print out the resulting "DVI" file. Note that you don't need
-%% to load any special Greek TeX format (*.fmt) file.
-%%
-%% If you are familiar with TeX, the macros at the top of the file have
-%% a few switches which you may want to set. If you have problems or
-%% can't run TeX at all, you may try to print the PostScript(TM) file that
-%% comes with it. In the worst case, you may write to Michael Doob and
-%% he'll send you a hard copy of his original English text (sorry, the
-%% translator cannot offer such a service!). You can also get a bound copy
-%% of the English original from the TeX Users Group (e-mail: tug@tug.org).
-%%
-%% Please, note that this translation is copyrighted by the translator. The
-%% complete copyright statement says:
-%%
-%% "The present document is distributed by the author and the translator
-%% in the hope that it will be useful to the reader. However, the author

-%% HISTORY
-%%
-%% Translation started: Jan. 1994
-%% First draft completed: Mar. 1997 (ver. 0.9)
-%% First public release (Internet): May 8, 1997 (ver. 0.992)
-%%
-%% Revisions:
-%%
-%% May 8, 1997 (ver. 0.993, not released): A few typos only.
-%% June 1, 1997 (ver. 0.994, released): Lots of typos corrected.
-%% Corrected the doubleside output macros.
-%% July 29, 1997 (ver. 0.995, not released): A few more typos.
-%% Feb 04, 1998 (ver. 0.996, released): Lots of typos corrected.
-%% Added a note on Greek stigma numeral.
-%% Feb. 05, 1998 (ver. 0.997, released): A few typos.
-%% July 27, 1998 (ver. 0.998, released): A few typos.
-%% Jan. 27, 1999 (ver. 0.999, released): Added info. about
-%% Syropoulos' Greek book on LaTeX.
-%% Mar. 20, 2001 (ver. 1.000, released): Final version. The next
-%% version is a printed book!
-
-%% Now here comes the code with the macros used in the manual. If you are
-%% already familiar with TeX, you may want to fiddle with them. In
-%% particular, the hooks are left to generate a new control word index and
-%% table of contents if you change section 1.2, or section 10.
