                               9 February 1997
 

SUMMARY
=======
 
This file contains instructions on how to install LaTeX for Web2c TeX
on the Amiga (AmiWeb2c).  Before reading this file, you should read
install.txt, which will explain how the LaTeX installation works, and
web2c.txt, which describes the UNIX version of this system.
 
This file describes:
 
 * How to save any old version of LaTeX.
 
 * How to configure LaTeX.
 
 * How to unpack the LaTeX distribution.
 
 * How to install the LaTeX files.
 
 * How to create the LaTeX format.
 
 * What to do if you have any problems.
 

REQUIREMENTS
============

In addition to the LaTeX distribution files, you will also need the
following:

 * the file `AmiWeb2c/texmf/tex/generic/local/hyphen.cfg' coming with the
   source distribution of AmiWeb2c, loading hyphenation patterns for US
   English (hyphen.tex aka ushyph1.tex) and UK English (ukhyphen.tex),
   and German (ghyph31.tex).  In the commentary section of `hyphen.cfg'
   a list of many other languages is given together with references to
   pattern files.  You may freely modify `hyphen.cfg' to suit your
   personal needs.


SAVING ANY OLD VERSION OF LATEX
===============================

Nobody should ever have installed LaTeX 2.09 with AmiWeb2c (which was first
released in April/May 1995), so there is no need for special treatment of
such an old version of LaTeX.
 
 
CONFIGURING LATEX
=================

During the installation procedure, it may be easiest to set some temporary
device names.

The LATEXINPUTS: directory is where the LaTeX base packages and classes
will finally be installed.  In the `TeX Directory Structure' assumed by
AmiWeb2c this defaults to:

   assign LATEXINPUTS: AmiWeb2c/share/texmf/tex/latex/base

The LATEXFORMAT: directory is where the LaTeX format is stored:

   assign LATEXFORMAT: AmiWeb2c/share/texmf/web2c

The LATEXDIST: directory is where the LaTeX distribution is stored:

   assign LATEXDIST: AmiWeb2c/share/texmf/source/latex/base

You should put all files coming with the base distribution of LaTeX in the
LATEXDIST: directory.  After the successful installation procedure, you
can safely remove the complete LATEXDIST: directory.

If you have installed the Amiga port of Web2c from scratch, you will
not have to edit the file texsys.cfg at all.  If you started with the
ready-to-use binaries, I suggest that you get either Martin Scott's
`UnixDirsII' commodity or Norbert Pschel's `DOSPrefs' commodity (my
favorite) from the Aminet.  The respective locations should be

   Aminet:/util/shell/UnixDirsII.lha
   Aminet:/util/misc/DOSPrefs22.lha

(The former archive is also available on Fred Fish's AmigaLibDisk 837.)
Either of these programs patch the AmigaOS so that the UNIX notations
`.' and `..' are enabled for the `current' and the `parent' directory
respectively.
 
 
UNPACKING THE DISTRIBUTION
==========================

To unpack the LaTeX distribution, you should:

   cd LATEXDIST:
   tex -ini unpack.ins

This takes about 12 minutes on a 50 MHz 68030, but considerably longer
on a standard 7.19 MHz 68000 (most likely several hours).  Why don't you
just go and make a good cup of coffee?  [Personal note: on a P5/133 under
the Linux operating system the very same task takes about half a minute.]

 
PUTTING THE FILES WHERE LATEX CAN READ THEM
===========================================

How was your coffee?  To install the LaTeX files created in the previous
step, you should:

   cd LATEXDIST:
   copy latexbug.tex testpage.tex lablst.tex idx.tex ltxcheck.tex +
      nfssfont.tex small2e.tex sample2e.tex docstrip.tex +
      #?.cls #?.clo #?.sty #?.fd #?.def #?.ltx +
   LATEXINPUTS:

(The `+' character means that you should type this as a single command.)

WARNING:  This single command line most certainly exceeds the maximum
length the AmigaOS is able to cope with!  Please, make sure that ALL these
files are correctly installed in `LATEXINPUTS:'.

If you have MakeIndex installed or intend to do so, copy #?.ist to the
MakeIndex inputs directory, which should be in TDS notation:

   AmiWeb2c/share/texmf/makeindex/styles

 
CREATING THE LATEX FORMAT
=========================

After the unpacked files of the LaTeX distribution are installed at the
appropriate place, you have to create the LaTeX format proper.  This will
conveniently be done by the following commands:

   cd LATEXFORMAT:
   tex -ini latex.ltx

Thus the format file latex.fmt will be created at the correct place and
also the correctness of the installation will be tested, because the
necessary files will be read from the appropriate paths.  If you intend
to use any of the advanced features provided by `enhanced TeX', like
left-to-right typesetting, you should instead use the commands

   cd LATEXFORMAT:
   tex -ini *latex.ltx

to create the format file.  (Note the asterisk in front of `latex.ltx';
this invokes a special feature of the tex binary, i.e., the `extended mode
of e-TeX 1.1'.)

You have now installed LaTeX!

 
GETTING A WORKING LATEX
=======================

Add the following lines to your User-StartUp file in the S: directory:

   alias ELaTeX  "tex &latex \language=\USenglish \input "
   alias GLaTeX  "tex &latex \language=\german \input "
   alias MyLaTeX "tex &latex \language=\<mylanguage> \input "

For the time being until you next reboot your system, you should type these
(and possibly other) commands on the command line input.  A list of aliases
that could serve as convenient examples is included in the file
`AmiWeb2c/texmf/source/amiweb2c/s/User-StartUp.entry' (or you can it
`execute' the whole script in your own `User-StartUp' file).

 
CHECKING THAT THE INSTALLATION WORKED
=====================================

To check that the installation worked, you should:

   cd LATEXFORMAT:
   latex ltxcheck

This will perform a number of tests, which should all report `OK'.
 
 
PROBLEMS
========

`texsys.cfg':  While running IniTeX on latex.ltx you might encounter the
   error message `! Bad texsys.cfg file: \@currdir .'  AmiWeb2c 2 comes
   with its own version of the `texsys.cfg' file, setting `\@currdir'
   to the UNIX-equivalent `./' notation.  By its very nature, the Amiga
   does not understand the `.' and `..' notation for the current and the
   parent directory.  In order to fix this situation you will have to
   install either (but NOT both!) of the commodities `UnixDirsII' and
   `DOSPrefs' before installing LaTeX (see the related section above).

`File missing':  As long as the default search paths of AmiWeb2c are
   correctly set up and used, you won't encounter this message.

`Font missing':  Some of the fonts, i.e., tfm files, required by LaTeX
   are missing.  In addition to the 75 standard fonts of the `Computer
   Modern' family, several additional fonts are needed.  Run MetaFont
   on the respective font drivers and install the tfm files in the
   AmiWeb2c/share/texmf/fonts/tfm// directory structure.

`Out of memory':  The memory configuration file `AmiWeb2c/bin/texmf.cnf'
   coming with the source distribution of AmiWeb2c was used for the
   installation of LaTeX on my system, so it should be appropriate for
   your machine too.  Since AmiWeb2c is directly descended from the UNIX
   Web2c distribution, its binaries are designed for a BigTeX configuration.
   If you really want to install it on machines with less than 8 MB of RAM,
   you will most likely have to restrict yourself to a single language in
   `AmiWeb2c/texmf/tex/generic/local/hyphen.cfg' and comment the value for
   `triesize' in `:bin/texmf.cnf' in order to start IniTeX.  Please do not
   request a SmallTeX version of AmiWeb2c, it just can't be done.


CLEARING UP
===========

You may now be wondering what to do with all the remaining files that are
not needed to run LaTeX.  This is, of course, a matter of personal taste
and availability of disk space but here is some guidance.

 * The files with extension .dtx, together with source2e.tex, can be used
   to typeset the documented source code (see texpert.txt for further
   information).

 * The files with extension .fdd contain the documented sources for the
   font definition files.

 * The files ltnews<xx>.tex and ltnews<xx>.ps both contain the lastest
   LaTeX newsletter.

 * The files with extension .txt contain information about (amongst other
   things) copyright, installation, patches and bug-reports; and those
   with extension .err contain errata lists for various publications:
   see 00readme.txt for further details.

 * The files with names of the form <xxx>guide.tex contain reference
   information convering only those features new to this version of LaTeX:
   they are not intended to be either a user guide or a complete reference.

 * The files with extension .ltx, together with latexcheck.tex, are used
   to create and test the format; therefore you should keep these together
   with the installed LaTeX system in the LATEXINPUTS: directory if you
   expect to remake the format before getting the next full distribution.

 * The files with extension .ins are used to unpack the code from the
   .dtx and .fdd files.

 * We recommend that you keep, in the LATEXFORMAT: directory, the
   transcript file latex.log that was produced whilst creating the format.

If you don't need the documentation or if you are lacking enough disk
space to permanently keep the LaTeX distribution files, you can now safely:

   delete LATEXDIST:#?
