Information concerning TeX and LaTeX in Hebrew.
***********************************************

Once you have a TeX-XeT installed, that is, TeX that knows the
commands 250 and 251 (I hope I am not mistaken) and can reverse
text, you can work in Hebrew, but you need some files to make
the job easy.  You also need fonts.

Things get more complicated because of two seperate systems of
Hebrew fonts: 7 bit fonts and 8 bit fonts, sometimes referred to
as Old Code and New Code, respectively.

If you work in Old Code, start your input file by
   \input heb_macros
   \sethebrew
You will then be using the fonts Jerusalem, TelAviv, OldJaffa
and/or DeadSea.

If you work in New Code, start your input file by
   \input heb_macros_newcode
   \sethebrew
   You will then be using the fonts xxxxx_newcode, where "xxxxx"
means the above font names.    

IBM PCs work with a third system of Hebrew fonts, 
to which I refer to as PC Code. 
However, this does not have to bother you.
The PC XeT program (the "Hebrew" TeX) inputs your PC Hebrew file
and turns it into an Old Code Hebrew file, so use
   \input heb_macros

fonts are supplied here in ../fonts

The macros files contained here are:
  heb_macros.tex    heb_macros_newcode.tex
  hebcal.sty        hebcal_newcode.sty

Once you have put the macros and the fonts in the right
places on your disk, run the file   ../tex_guides/hebtex_guide.tex
The guide contains explanation pertaining to TeX in Hebrew, the available
keywords and fonts.  The guide is in hebrew Old Code.

An alternative one page guide with Hebrew keywords is
	 hebrew_cs_guide
This guide is in English, but in order to print it you need
the Jerusalem font.

The most important keywords in Hebrew TeX are 
\sethebrew       \L{English string ....}
\unsethebrew     \R{Hebrew string .....}

To work in LaTeX in Hebrew, copy the files:

    hebrew.sty           hebcal.sty          for Old Code;
or
    hebrew_newcode.sty   hebcal_newcode.sty  for New Code.

Hebrew is an option in latex ; you specify, for example,
\documentstyle[hebrew,......]{article}   %  In Old Code
\sethebrew
\begin{document}

or
\documentstyle[hebrew_newcode,......]{article}   %  In New Code
\sethebrew
\begin{document}

The availabe Hebrew fonts in LaTeX are:

  Jerusalem  --  called for short \jm
  TelAviv    --  called for short \ta
  DeadSea    --  called for short \ds
  OldJaffa   --  called for short \oj

  The Hebrew option in LaTeX uses these fonts.
  When you set hebrew mode (via \sethebrew)
  the following setting comes into effect:

  \jm replaces \rm   (The regular font)
  \ds replaces \bf   (boldface)
  \oj replaces \it   (italics)
  \ta replaces \tt   (typewriter)

This is done in the line
\def\tohebrew{\def\rm{\jm}\def\bf{\ds}\def\it{\oj}\def\tt{\ta}\jm}
(in hebrew.sty)

You can change the setting by changing this line in hebrew.sty
and/or in hebrew_newcode.sty .
