+		INSTALLATION NOTES FOR GreekTeX v 3.1
+		-------------------------------------

+
+
+	This document describes how to get GreekTeX up and running
+	on your system. It is devided into two parts: instructions
+	for Unix users and Instructions for DOS emTeX users. I would
+	like to hope that these two categories represent a majority
+	of TeX users and I apologize for not extending specialised
+	instructions to users of other systems. For those of you that do
+	not fall in the two categories do not panic! Read the DOS
+	section and procede with the same steps. Just change the
+	paths and executables to match the ones in your system.
+	
+
+Part A: 	Unix Users
+--------------------------
+
+	What you need: 
+		To rebuild the whole GreekTeX package you need to have
+		access to the metafont and initex programs as well
+		as the ability to integrate new fonts and formats
+		to the search path of the local tex distribution.
+		You also need the gftopk utility for transforming
+		mf output to dvi readable form. For automated installation
+		you need a "standard" unix 'make' program, and the
+		'dc' calculator. If you do not have any of these you
+		will have to do the job by hand. If you do not have
+		the dc calculator you can still build the fonts
+		by altering the script to suit your own needs.
+		You also need to know the resolution of the local
+		printer. Finally you can do with a bit of patience.
+
+	Procedure:
+		The installation procedure follows the steps:
+			* build and install the fonts in the
+			  standard path (both pk and tfm files)
+			* build the greek format files for both
+			  greekTeX and grlatex.
+			* place the files in the appropriate 
+			  directory
+			* do a test run to see how it looks!
+
+	How to procede for an automated installation:
+	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+	STEP			DESCRIPTION
+	-> 0	Find a suitable place to unpack the file
+		kdgreek3.1.tar.Z. Let us call the subdirectory
+		kdgreek3.1/ where all the files will be the
+		TOP directory.
+	-> 1	First edit the file unix/newfont. If a similar
+		script exists in your system the just forget it
+		and mode to the step 2. In particular set the
+		default paths and executable names to point
+		to the right direction and make sure the file
+		has the execute attribute set.
+	-> 2	Edit the Makefile at the TOP directory to 
+		reflect the paths and setting of your own system.
+		It should be easy and straightforward and not many
+		changes should be needed in a standard distribution.
+	-> 3 	Make the fonts: at the shell prompt type
+			make fonts
+		This will try to create the greek fonts for all
+		needed magnification levels and place them at
+		their proper place (all the job is done by the
+		newfont script in the unix directory or the
+		newfont script that you set in the makefile).
+		Do not be alarmed if "stange Pos " occur at some
+		fonts and magnifications. The fonts are still in
+		experimental stage and do have problems. If your
+		version of metafont stops at a '?' prompt just
+		hit return to continue.
+	-> 4	You can now build the formats. give the command
+			make formats
+		this will build both greek.fmt and lgreek.fmt in
+		the build subdirectory. Log files will be in the
+		log subiderctory of build.
+	-> 5 	Install everything in its proper place by 
+		executing the command:
+			make install
+		This will place everything in the proper place
+		and have you ready to go.
+	-> 6 	Try the system out: go to the doc doc subdir
+		and type 
+			greektex usage
+		then see what happens.
+	
+
+Part B: 	DOS emTeX users
+-------------------------------
+
+	What you need:
+		In order to use GreekTeX on a PC running DOS and emTeX
+		you will need mf and friends to create the fonts (mfjob
+		for automated procedures) plain tex and latex bearing
+		version 3.0 or later (that is the format file not the
+		executable). 
+
+	How to procede:
+		Unpack the distribution where convenient. If you got
+		GreekTeX as greektex.zip the use [pk]unzip -d greektex
+		at an apropriate directory. You can delete the unix,
+		utils directories and the makefile since they are
+		intended for unix users. 
+
+	-> 1	Copy the file emtex/kdgreek.mfj to the MFJOB path or
+		in the mf directory. cd to the mf directory and
+		give the command mfjob -i kdgreek. If everything goes
+		well you will end up with a new bunch of fonts in
+		the proper directories.
+	-> 2	cd to tex and type
+			tex -i -8 greek \dump
+		This will create the files greek.fmt and greek.log
+		Move greek.fmt to the directory where you normally 
+		store the format files (e.g. emtex/btexfmts) and 
+		delete the file greek.log after reviewing the messages.
+	-> 3	cd to latex and type
+			tex -i -8 lgreek \dump
+		Repeat the same procedure as in step 2 for copying the
+		lgreek.fmt and removing the lgreek.log file.
+	-> 4	copy the files in the tex, latex directories to the
+		default search path of emtex (e.g. /emtex/inputs)
+		If you will be using a greek ISO character set for
+		modern greek you might also want to copy the files
+		emtex/greek.* to your inputs dir.
+	->5	Finally move the emtex/*.bat files to the emtex bin
+		directory and you are all set to go.
+	->6	Test the system by cd to doc and doing
+			greektex usage.tex
+		
+	GOOD LUCK
+
+Please send comments and bug reports to kd@doc.ic.ac.uk
+
+DISCLAIMER: 
+	Although I have put much effort in eliminating bugs, the
+	greekTeX package is still in experimental phase. If you 
+	decide to use the package please do not blame me for any
+	problems that may arise from its use. I cannot be held
+	responsible for any problems and I cannot gurantee 
+	bug fixes (although I guarantee that in due time I will
+	look over all reports and suggestions).

+		 GreeKTeX Ver 3.1 Distribution
+		 -----------------------------
+
+		   	K J Dryllerakis
+		   Logic Programming Group
+		   Imperial College,London
+		        kd@doc.ic.ac.uk
+
+What it is:
+	GreekTeX is a complete package for typesetting greek
+	(modern or ancient) texts within the framework of 
+	plain TeX or LaTeX. It supplies a set of fonts based
+	on the excellent ones originally developed by
+	Sylvio Levi in the States and the modifications made
+	thereafter by Haralambous in France. 
+	The approach adopted is different from both the
+	previous ones since it uses full 256 character fonts 
+	and ligatures as the principal method of accenting
+	or "breathing" letters. This makes the macros more
+	robust and easier to use within TeX and LaTeX 
+	environments.
+
+------------------------------------------------------------------------
+Note: Two different packages are included in this distribution. (Both
+      based on the same set of fonts).
+	* greektex : an extension of plain tex 
+	* grlatex  : an extension of LaTeX for greek texts.
+------------------------------------------------------------------------
+
+What it Includes:
+	> a complete set of fonts (regular,bold,italic)
+	> for working with plain tex a file to be included
+	  which will import the macros and fonts needed
+	  to add greek texts within your normal documents
+	  (greektex.tex)
+	> for working with an extension of plain tex 
+	  a set of macros allowing the usage of greek
+	  within specific environments and hyphenation
+	  patterns for the greek langugage. Choosing
+	  to use this option will mean that you will develop
+	  the formatting of your text by yourself.
+	  (command greektex)
+	> for working with  LaTeX a style option that allows
+	  entering greek text within specific environments
+	  (all standard latex command still work e.g. font
+	  size changing). For typesetting texts mainly in
+	  greek a new format file which combines the greek
+	  enviroment with hyphenation patters and an optional
+	  global greek mode.
+	  (command grlatex)
+	> A set of utilities that allow the conversion of extended
+	  ASCII greek ISO character files to a format understandable
+	  by grektex and grlatex. (filter as C-source or emTeX filter
+	  table for use with texconv)

+------------------------------------------------------------------------
+
+Important Note:
+^^^^^^^^^^^^^^^
+	If you are building the greek extension of the LaTeX format
+note that the old font coding scheme is used. The package -although it
+will create a proper Format file- will not run properly under the 
+Mittelbach convention for font loading. In order to check
+which on you have see your lfonts.tex file! (To make sure that
+you do not have to retrieve the standard lfonts.tex I have included in
+the latex directory -- please note the copyright notices for this file).
+
+
+Hope you enjoy the package. Please send any comments or bug reports

+.TH GRLATEX "7 Dec 1992"
+.SH NAME
+grlatex \- tex formatting and typesetting (greek option)
+.SH SYNOPSIS
+.B grlatex
+[options] [filename]
+
+.SH DESCRIPTION
+.I grlatex
+is part of the 
+.B GreekTeX 
+package for typesetting greek texts under the TeX typesetting system.
+.I grlatex 
+is an extension of the LaTeX macro package for
+the TeX mathematical typesetting package. The extension
+consists of a new set of language dependent macros,
+a set of hyphenation patterns for the greek language,
+and a set of macro development tools for the greek languge.
+.PP
+.I	grlatex 
+can be used instead of the latex package to typeset
+any source file written for the LaTeX macro package. In addition
+a special greek environment is defined inside which latin 
+characters correspond to greek ones according to the scheme
+.PP
+.B 	a b g 
+.B d e z 
+.B h j i k l m 
+.B n x o p r s 
+.B t u f q y w 
+.B and c (final s)
+.PP
+In order to get accents and breathing use ',`,~,>,< before any
+vowel. For those typesetting ancient greek texts iota subscript
+can be generated by placing the character | after the vowel to
+recive the subscript.
+.PP
+The greek environment is created by the command
+.PP
+	\\begin{greektext}
+.PP
+and ends by
+.PP
+	\\end{greektext}.
+.PP
+Inside the greek environment the font families available are:
+.RS
+.TP
+		\\gr	Classic Greek
+.TP
+		\\grbf	Boldface Greek
+.TP
+		\\grsl	Slanted Greek
+.TP
+		\\grit	Greek Italics
+.TP
+		\\grtt	Typewritter Greek
+.RE
+.LP
+Note that all the font scaling commands will affect the greek
+characters as well. Nevertheless if the font size is changed
+inside the environment, the effects are only local.
+
+.SH "STYLE FILES"
+
+Special style files exist for writting texts in greek language.
+The names of the style files are derived from the latex ones
+by preciding them with the suffix `gr' (e.g. grarticle.sty)
+Any such style causes latex to enter a permenent greek environment.
+The original latin (global) environment is locally available
+through the commands \\begin and \\end {latin}.
+Note that the roman font families are normally accesed in the 
+standard way e.g. {\\rm Latin Word}. Beware the difference in 
+certain symbols; all the accentuation symbols are concidered
+as letters (catcode 11).
+
+.SH "MACRO DEVELOPMENT"
+
+If you are interested in creating macros while in greek mode
+try to remember that certain symbols need to be replaced by more
+general control sequences:
+.RS
+.TP
+			$ ---> \\ m@thm@de
+.TP
+			> ---> \\ gt (greater than)
+.TP
+			< ---> \\ lt (less than)
+.RE
+.LP
+.SH "SEE ALSO"
+.BR tex(1), 
+.BR latex(1),
+.BR greektex(1).
+
+.SH FILES
+For more information on macro development under the package
+see the extensive discussion in the comments of the macro
+files: lgreek.tex, grfonts.tex, greek.sty, gr*.sty
+
+.SH "AUTHOR"
+	The 
+.B GREEKTeX 
+package was developed partly from 
+ideas of Sylvio Levy and Haralambous by K J Dryllerakis

+%INSTALLATION PROCEDURE FOR KD FONTS
+\magnification=\magstep1
+\parindent=0pt
+\centerline{\bf INSTALLATION PROCEDURE}
+\smallskip
+\centerline{\bf FOR Greek\TeX\ PACKAGE}
+\bigskip
+\centerline{\bf NOTE: This document does not describe installation of %
+the grlatex part of the package}
+\bigskip
+This documents gives a brief description of the installation
+procedure of the Greek\TeX\ Package. It is assumed that \TeX\ version
+3.0 or higher is installed in your system and you also have access to
+Metafont (v 2.00 or higher). Most of the systems are also equiped
+with a scirpt, or batch file or even a small program that will create
+a font at a given magnification with a single command. Let us assume
+that this command is {\tt newfont} $<FontName>$ {\tt scaled}
+$<Magnfification>$. You must also have access to {\tt plain.tex} and
+{\tt hyphen.tex} (plain format version 3.00)  or higher, as well as
+to INITEX for building formats. If you are interested in building
+the grlatex format as well, the the files for building lplain must
+also be available.
+
+\medskip
+\leftline{\bf Installing the Fonts}
+\smallskip
+Here is a table of the fonts and suggested magnifications:
+$$\vbox{\divide\hsize by2
+\halign{\strut\tt #\hfill\tabskip=2em&\hfil#\hfil&\hfil#\hfil&\hfil#\hfil&%
+\hfil#\hfil&\hfil#\hfil&\hfil#\hfil&\hfil#\hfil\cr
+&750&800&900&1000&1200&1440&1795\cr
+kdgr10&&&&*&*&*&*\cr
+kdgr9&&&&*&*&*&*\cr
+kdgr8&*&&&*&*&*&*\cr
+kdbf10&&&&*&*&*&*\cr
+kdbf9&&&&*&*&*&*\cr
+kdbf8&*&&&*&*&*&*\cr
+kdsl10&&*&*&*&*&*&*\cr
+kdti10&&*&*&*&*&*&*\cr
+kdtt10&&*&*&*&*&*&*\cr
+}}
+$$
+Each font is installed by a command of the form\par
+{\tt newfont kdgr10 scaled 1200}\par
+After installing all the fonts you are ready to move to the
+installation of the greek format.
+\medskip
+\leftline{\bf Format Installation}
+\smallskip
+Make sure that the file {\tt plain.tex} and {\tt hyphen.tex} are in
+your path and enter the command:\par
+{\tt INITEX greek}\par
+When INITEX has finished enter {\tt $\backslash$ dump}. Hopefully the file
+{\tt greek.fmt} must be ready to use. Just place it in your \TeX\ path
+and issue the command\par
+{\tt tex \& greek foo.tex}\par
+to run GREEK\TeX.
+
+You can also place the file {\tt greektex.tex} in you TEXINPUT path
+so that it can be included in short greek documents or replace the
+greek format file if the latter does not exist in your system. Note
+that the hyphenation will only work under the greek format and {\bf
+not} when you include the {\tt greektex} file to your document.
+Hyphenation apart, no other differences exist between the greek
+format and {\tt greektex.tex}.
+
+
+If you are building the latex extension grlatex, issue the command:\par
+{\tt INITEX lgreek}\par
+This will built the lgreek format. The lgreek format can be used
+instead of the standard latex format since it is simply and extension
+of the latex package enriched with several language dependant macros
+and the hyphenation patterns for greek tex. 
+
+If during the procedure of creating the greek latex INITEX complains
+about too many font families then the lplain format must be modified
+to define only 10 font families (older version of lfonts.tex defined
+the {\tt uit} family of fonts which you might be able to eliminate
+without mamy losses).
+

+
+	This document describes \greektex, yet another something-\TeX\
+application, a package for typesetting greek texts. The following
+pages are intended to be a quick tutorial on the package and not a
+detailed account of the package. It is assumed that the \greektex\ 
+package is already installed at you site and both the greek format
+file (|greek.fmt|) and the alternative \greektex\ macros
+(|greektex.tex|)  are accesible to the user. We also assume that all
+the recomended |kd| fonts exist in the font path. If this is not the
+case please consult the installation procedure document which gives
+all the information needed to install the package in your site. In
+the discussion to follow, more \TeX nical material is presented in a
+finer print.
+
+\section{The Greek Mode And Fonts}
+
+	In order to typeset greek text, you have to advise \TeX\ to
+enter a ``Greek Mode''\footnt{The idea of a ``greek environment'' was first
+introduced by Sylvio Levi in his greek fonts; the top level macros of
+our package are inherited from this first approach.}. Entering the
+greek mode is achieved by typing |\begingreek| at the position were
+we want the greek text to begin. The greek mode will be active until
+an |\endgreek| is typed, when we return to the previous state. Inside
+the greek mode, the latin characters typed correspond to the greek
+alphabet and diacritic marcs. The family changing commands (|\sl|,
+|\bf|, |\tt|, |\it|) are automatically switched to correspond to the
+proper greek font families and the classical greek font corresponds
+to the |\gr| or |\rg| command. Roman letters are still available
+through the |\rm| and |\l|{\it oldsequence\/} commands (e.g. |\lsl|).
+When we re-enter the greek mode, the font used last is remembered and
+typesetting continues from the state we left of in the previous greek
+mode.
+\beginFine
+	\TeX nically, entering the greek mode means {\it i\/}. to redifine the
+|\catcode| values for several characters (mostly accents and
+breathing symbols), {\it ii\/}. to declare that we are currently
+typesetting in greek and use the correct hyphenation tables, {\it
+iii\/}. switch to the point size and font used last, and {\it iv\/}.
+redifine the control sequences corresponding to font family switching
+(e.g. |\sl| etc.).
+\endFine
+The font families that are currently avaible are all based on the
+original designs by Sylvio Levi and Haralambous. The families (and
+the corresponding font switching commands) are: classical greek
+(|\gr| or |\rg|), slanted greek (|\sl|), greek italics (|\it|),
+boldface greek (|\bf|) and typewriter greek (|\tt|). Remember that
+these families are only available inside greek mode.
+\beginFine
+	A set of point-setting commands are made available from the
+greek format. Three sizes are prespesified for ten, nine, and eight
+points respectevly. The corresponding commands are |\grtenpoint|,
+|\grninepoint|, and |\greightpoint|. Since not all fonts exist in the
+sizes need, scaled fonts are used instead. Remeber that re-entry in
+the greek mode means picking up from exactly where we previously left
+i.e. from the same point size. If point-size changes are to remain
+local the user is encouraged to enclose them in groups.
+
+	The real names for the control sequences switching to greek
+font families are |\gr|, |\git|, |\gsl|, |\gbf|, |gtt|. These
+commands  can be used even outside greek mode to typeset greek short
+texts but it is not recomended. Note that the \LaTeX\ version of
+\greektex\ (the greek style file |greek.sty|) uses only these font
+changing commands.
+\endFine
+Since the commands |\begingreek| and |\endgreek| can be quite tedious
+to repeat, they can be both substituted either by the character |$| or
+{\tt\|} if at the beginning of your file you specify
+|\greekdelims{dollar}| or |\greekdelims{bar}| repsectively. In case
+the |$| character is used, math mode is accessed by the control
+sequence |\math|.
+
+\section{The Greek Alphabet}
+
+	Since \TeX\ was designed to help portability of files, most
+implemetations support only 128 character input (file transfer is
+also based on the 128 ascii set). That means we have to use the Latin
+alphanumeric characters to represent the greek ones. The following
+scheme is used to represent greek characters inside the greek mode:
+\math\math
+\hbox{\valign{
+  \hbox to 10pt{\hfil\strut$#$\hfil}&\hbox to 10pt{\hfil\strut\tt#\hfil}\cr
+  a&a\cr b&b\cr g&g\cr d&d\cr e&e\cr z&z\cr h&h\cr j&j\cr
+  i&i\cr k&k\cr l&l\cr m&m\cr n&n\cr x&x\cr o&o\cr p&p\cr
+  r&r\cr c&s\cr t&t\cr u&u\cr f&f\cr q&q\cr y&y\cr w&w\cr
+  c&c\cr}}
+\math\math
+\beginFine
+	It is a common practise in Greece to substitue the characters
+corresponding to the higher
+ascii codes by greek characters so that users are able to see the
+greek characters directly on the screen. It is fairly easy to write a
+program to transform any such ascii output to the corresponding
+``latin'' representation of the greek characters and feed it directly
+to \TeX 's mouth. For example such a translation program is supplied
+with the current distribution of the em\TeX\ package for DOS based
+machines.
+\endFine
+
+\section{Accents, Breathing And Punctuation}
+
+	Three different accents are encountered in greek texts. In
+order to accent a vowel simply type |'|, |`|, or |~| to get an acute,
+grave or circumflex accent repsectively. Breathing signs are achieved
+in the same way by preceding the vowel (and any accent that it may
+have) with |<| for rough and |>| for
+smooth breathing. Breathings can also be used before a greek rho
+($r$). Iota subscript is achieved by typing {\tt \|} {\it after\/}
+vowel. The diairesis sign is achieved by presiding a (maybe accented) 
+vowel by |"|. Greek punctutation marcs are achieved according to the
+following table:
+\math\math
+\hbox{\valign
+  {\hbox to 15pt{\hfil\strut$#$\hfil}&\hbox to 15pt{\hfil\strut\tt#\hfil}\cr
+  .&.\cr ,&,\cr ;&;\cr :&:\cr !&!\cr ?&?\cr ''&''\cr ((&((\cr ))&))\cr}}
+\math\math
+For example, concider the following quotation from Xenophon :
+\bigskip
+{\narrower\narrower\noindent$>En o>udem'ia g'ar p'olei t`o b`eltiston e>'unoun >est`i t~w|
+d~hmw|, >all`a t`o k'akiston >en <ek'asth| >est`i p'olei e>'unoun
+t~w| d~hmw|; o<i g'ar <'omoioi to~ic <omo'ioic e>'unoi e>isi.$\par}
+\bigskip
+\noindent was typeset by \par
+\medskip
+\math\math
+\vbox{\advance\hsize by-40pt\parindent=0pt\noindent
+\obeylines
+|>En o>udem'ia g'ar p'olei t`o b`eltiston e>'unoun >est`i t~w|{\tt\|}
+|d~hmw|{\tt\|}|, >all`a t`o k'akiston >en <ek'asth|{\tt\|}| >est`i|
+|p'olei e>'unoun t~w|{\tt\|}| d~hmw|{\tt\|}|; o<i g'ar <'omoioi to~ic|
+|<omo'ioic e>'unoi e>isi.|
+}
+\math\math
+\noindent Note the use of punctuation and breathing marks before the
+vowels.
+\beginFine
+All accents and breathings are recognised as normal letters insode
+the greek mode. They will print for themselves when they stand alone
+but form ligatures when preciding a vowel. The ligatures do all the
+work for us; the kerning between accents or breathing and capital
+vowels is also done through kerning. This simplifies the macros used
+and the greek character set is usable with only a few |\catcode|
+definitions. All the rest of the mechanisms supplied in the greek
+format are only to facilitate the usage of the fonts in standard text 
+and macro creation.
+\endFine
+
+\section{Hyphenation}
+
+	If you are working with the greek format file, then correct
+hyphenation is assured for greek text. The hyphenation patterns
+supplied in the file are the ones compiled by Haralambous in France.
+If you are working with the file |greektex.tex| then no hyphenation
+patterns are loaded; this fact makes the macros of |greektex.tex|
+suitable for only small greek texts. \greektex, takes full advantage
+of the multilingual characteristics of \TeX\ version 3.0 or higher by
+declaring a new language and identifying the correct patterns for this
+new language. The result is correct hyphenation for texts containing
+both greek and latin texts.
+\beginFine
+In case you want to use \greektex with another multilingual package,
+it is important to find out the limitation of your \TeX version. It
+is possible that the number of allowed hyphenation patterns exceeds
+the number needed. Remember that plain \TeX\ uses 4447 patterns and
+\greektex\ needs a futher 1170.
+
+It is possible to see the proposed hyphenation for a word using a
+macro similar to |\showhyphens| (supplied with plain \TeX). The macro
+|\showgreekhyphens| can be used succesfully only inside greek mode.
+This is due to the fact that the argument for the macro has to be
+scanned with the correct |\catcode| values active.
+\endFine

+\exparagraph Let us try to typeset this poem written by a greek poet
+of the 20th century. The peculiar format is the original one required 
+by the poet. It is immediatly apparent that a command taking two
+arguments can be used to typeset each verse; the arguments will be
+the left and right part of each verse. The only important problem
+encountered is the following: when \TeX\ is reading the
+arguments of a command, it immedietly assigns |\catcode| values to
+the tokens read. So, if the correct |\catcode| values are not active
+at the time the arguments are scanned, \TeX\ is much confused.
+Consequently, macros that take as arguments greek text must be called
+from within greek mode. Having that in mind we can define a macro
+|\verse| that will correctly typeset one verse of the poem. The macro
+is defined as follows:
+\smallskip
+\hbox to\hsize{\hss|\def\verse#1#2{\line{#1\hfill#2}}|\hss}
+\smallskip
+\noindent It is assumed of course that the |\hsize| required
+for the document is already set. The rest is easy.

+\exparagraph \tolerance=2000 Let us now turn to our second example which will demonstrate
+scientific typesetting in greek. The example is taken from the book
+{\it Classical Mechanics\/} by T.W.B. Kibble in its greek
+translation. Let us suppose that we are trying to typeset this book;
+how would we go about to build the macros needed? First of all we
+will be using a lot of math formulae and therefore we are in
+desperate need of the start and end math symbol. Since we are using
+modern greek and no iota ligatures are needed, we can redifine the
+bar {\tt\|} to stand for the begin and end greek by
+|\greekdelims{bar}|. This might turn out to be convenient if we
+want to include latin words in the text. Now for the macros.
+Starting with the
+headline appearing at the top of the page we need to define the
+|\headline| macro. This must be done within greek mode to correctly
+interprent the tokens scanned:

+It might be wiser to change the |\git| command either to 
+|\grtenpoint\git| or |\tengri| to ensure that the correct font is
+selected when the output routine is called.
+
+To typeset math formulae you only have to use the standard \TeX\
+rules. Even within greek mode entering the math mode has exactly the
+same effect as from the plain \TeX\ mode. This is not entirely true
+since the font changing sequences are redefined. If you want boldface
+characters within the math mode you have to use the |\lbf| command
+and the same for any other family. See how is it really is:

+\section{Final Remarks}
+
+	Except from the macros explained above, the greek format also
+has a set ofgeneral use macros. It is possinble that in certain
+cases, greek mode will be the dominant mode. To switch to a permenant
+greek mode use the command |\setgreek|. If you want to restore the
+original \TeX\ mode (including restoring any reassignents of |$| or 
+{\tt\|}) use the command |\setlatin|. 
+\beginFine
+	These commands are based on the internal commands
+|\gr@@km@de| and |\l@tinmode|. Both define the |\catcode|s for the
+mode. A macro-builder can use them to create different environments
+e.g. a command to switch to english from a global greek mode. Just
+remeber that you will be on your own so you will have to switch to
+the enclish language manually by a command |\language0|.
