install.txt for amslatex 2.0 [1999/12/17]

To begin with we assume that you have a relatively up-do-date TeX system
with a texmf directory named something like /usr/local/share/texmf or
c:\sw\texmf. For Textures or OzTeX see Section III.

The first step is to identify the ROOT directory of your texmf area for
installation:

  If your texmf directory
  is named:                    Then ROOT is:
  -----------------------      ---------------------------
  /usr/local/share/texmf       /usr/local/share

  c:\sw\texmf                  c:\sw

In the following instructions, wherever you see ROOT substitute the
directory prefix that is used on your system, and substitute \ or :
for / if appropriate.

If this terminology doesn't make sense to you, seek assistance from
a friend or colleague, or from the company that you bought your TeX
system from, or contact us at

========================================================================
I. Installing the easy way.

1. Download the following archive file:

   ftp://ftp.ams.org/pub/tex/amsltx2.tgz

There are also .tar.Z and .zip files for those who prefer those formats.

2. View the following files to assess the effects of the upgrade on your
system:

  texmf/source/latex/amsmath/diffs-m.txt
  texmf/source/latex/amscls/diffs-c.txt

3. Remove the old version of amslatex or move it out of the main LaTeX
search path. For example:

   Move ROOT/texmf/tex/latex/amslatex
     to ROOT/texmf/source/latex/amsltx12/inputs

4. Extract files using the texmf root directory as the "Extract to"
target. [If it is important for you to conserve disk space, see the
remarks in step 5.] Some typical examples:

WinZip: Click on "Extract" and then in the "Extract to" box, enter
        c:\sw (or whatever ROOT is on your system)

gzip:   gzip -dc amsltx2.tgz | (cd ROOT; tar xvf -)

unzip:  unzip -d ROOT amsltx2.zip

To check the end result, you should find that you now have amsmath.sty
in the following location

  ROOT/texmf/tex/latex/amsmath/amsmath.sty

If you have a teTeX system you may need to run mktexlsr [texhash] to
update the TeX file lookup database.

5. Some files will appear in both the texmf/source area and another
area. This is because the source form and the in-use form are identical.
As distributed, the files in the texmf/source/latex/ams* areas comprise
a complete copy of the distribution from which all the other files can
be regenerated if need be. If you need to conserve disk space, you could
delete the files in the texmf/source area since they are not needed for
normal use; alternatively, you could in step 4 selectively unpack only
the subdirectories texmf/doc, texmf/tex, texmf/bib, and texmf/bst. Or
you could elect to make use of soft link capabilities if your system has
them.

========================================================================
II. Installing the hard way.

Get math.zip and classes.zip from CTAN, directory

  tex-archive/macros/latex/required/amslatex

and follow the instructions in their respective install.txt files.

========================================================================
III. Macintosh (Textures or OzTeX) installation.

1. Download a .zip archive from the AMS:

   ftp://ftp.ams.org/pub/tex/amsltx2.zip

2. Use StuffIt or similar application to view the following files inside
the archive and assess the effects of the upgrade on your system:

  texmf/source/latex/amsmath/diffs-m.txt
  texmf/source/latex/amscls/diffs-c.txt

3. Determine the location of your LaTeX inputs folder and LaTeX
documentation folder. Typical values are:

  OzTeX:TeX:Inputs:LaTeX:
  OzTeX:TeX:Docs:LaTeX:

or

  Textures:TeX inputs:*LaTeX:           (where * is a bullet character)
  Textures:LaTeX support:LaTeX Documentation:    

4. [Optional] Move existing files from AMS-LaTeX 1.2 to another folder
for fallback purposes. This would include the following files in your
LaTeX inputs folder:

  amsart.cls         amsopn.sty 
  amsbook.cls        amsproc.cls
  amsbsy.sty         amstex.sty 
  amscd.sty          amstext.sty
  amsdtx.cls         amsthm.sty 
  amsgen.sty         amsxtra.sty
  amsldoc.cls        upref.sty  
  amsmath.sty

The 1.2 release of AMS-LaTeX will remain available from the AMS for
reference.

5. Find the texmf/tex/latex/amsmath folder in the zip archive and
extract its contents into your LaTeX inputs folder. Do the same for the
texmf/tex/latex/amscls folder.

6. Find the texmf/doc/latex/amsmath folder in the zip archive and
extract its contents into your LaTeX documentation folder. Do the same
for the texmf/doc/latex/amscls folder.
