install.txt for amslatex 2.20 [2004/10/22]

Update [2002-02-05]: Files added for the "amsrefs" package.

If you have a relatively up-do-date TeX system that complies with the
TeX Directory Structure (TDS) standard, installing according to the
instructions in section I below is the easiest method.  See

    http://www.tug.org/tds/tds.pdf

for details on the TDS standard.  If your TeX system does not comply
with the  TDS standard, please contact the manufactuer of your TeX
system for details on how to install third-party TeX packages.

The first step is to identify the TEXMF folder that contains files used
by LaTeX. To do this, look for the file article.cls. If you find, e.g.,

  /usr/local/share/texmf/tex/latex/base/article.cls

then we will define TEXMF to mean /usr/local/share/texmf (everything
up to the /tex/latex/base part). On a Windows system the file location
will probably be something like

  c:\sw\texmf\tex\latex\base\article.cls

Then we define TEXMF to mean c:\sw\texmf. In the following instructions,
wherever you see "TEXMF" substitute the folder name determined in this
way.

If this terminology does not 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/amslatex.zip

For the amsrefs package, download also

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

and carry out step 4 (steps 2 and 3 can be skipped).

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

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

3. Backup the old version of AMS-LaTeX, preferably by moving it out of
the TEXMF tree.

4. Extract files from the .zip archive using your favorite unzip tool, setting
the extraction target directory to the texmf root directory.

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

  TEXMF/tex/latex/amsmath/amsmath.sty

Some TeX systems also use a database to keep track of TeX input files.
If this database is not updated, your TeX system might not find the
newly installed files.  Consult your TeX system's documentation to
determine how to update this database.

6. Some files will appear in both the source area and another area.
This is because the source form and the in-use form are identical.
As distributed, the files in the 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 source area, since they are not needed
for normal use.

========================================================================
II. Installing the not-so-easy way.

Get the following zip archives:

ftp://ftp.ams.org/pub/tex/amscls.zip
ftp://ftp.ams.org/pub/tex/amsmath.zip
ftp://ftp.ams.org/pub/tex/amsrefs.zip

Unpack the zip archives and follow the instructions in their respective
install.txt files.
