AMSFonts 2.2 READ.ME                                           January 1995
This is a documentation file to accompany the AMSFonts 2.2 distribution.

Copy all of the files in this directory (/pub/tex/amsfonts) and the following
subdirectories, into a corresponding directory tree on your system:

      All users:
               /pub/tex/amsfonts/plaintex
               /pub/tex/amsfonts/doc
               /pub/tex/amsfonts/doc/latex
               /pub/tex/amsfonts/latex
               /pub/tex/amsfonts/tfm

      Users of Cyrillic text:
               /pub/tex/amsfonts/alt-cyr

      Users who wish to use .pk files provided with the distribution:
               appropriate subdirectories of /pub/tex/amsfonts/pk-files,
               depending on resolution of output device

      Users who wish to generate their own .pk files:
               /pub/tex/amsfonts/sources and its subdirectories

Read the section below, "Installing AMSFonts 2.2 on your system," for
instructions for correct installation.

If you are preparing to obtain the files in this distribution by ftp,
please note that transmission time can be improved by getting the files
in compressed format, if you have the necessary unpacking tools at your
end.

From a CTAN archive, you can for example request dirname.zip to get the
contents of any directory in zipped form, and similarly for other common
compression formats; see the CTAN help information for more details.
(NOTE: subdirectories are automatically included; but in the case of the
AMSFonts distribution you should be careful to avoid retrieving all the
pk-files subdirectories, as they contain hundreds of files and it's
highly unlikely that you will require them all.)

From the AMS archive at e-math.ams.org, .tar.Z or .tar files for
various common selections are available in the parent directory `ams'. 
To unpack these you need `tar' and `uncompress' programs.

-----------------------------------------------------------------

What changes were made between AMSFonts 2.1 and AMSFonts 2.2?

The primary change is the inclusion of LaTeX support macro files as
part of the AMSFonts distribution. The files in the "latex" subdirectory
of this directory are compatible with LaTeX2e, the current LaTeX standard.
Users of LaTeX 2.09 are strongly encouraged to upgrade to LaTeX2e, as
we do not support the use of AMSFonts with LaTeX 2.09.

The only significant change to the characters in the fonts was a bug
fix which corrected an anomaly in the Blackboard Bold N character from
the MSBM fonts. That character printed incorrectly at a few
resolutions (including 600dpi), and it now prints correctly at all
resolutions. The metrics for AMSFonts 2.2 are not different from those
for AMSFonts 2.1. 

There has also been a slight change to the file amssym.tex, and very
significant changes to the User's Guide.

-----------------------------------------------------------------

INSTALLING AMSFonts 2.2 ON YOUR SYSTEM

1. Installing the fonts:

The files from the appropriate subdirectory of the pk-files
subdirectory of this directory (/pub/tex/amsfonts/pk-files/dpi118 for
118dpi fonts, /pub/tex/amsfonts/pk-files/dpi180 for 180dpi fonts,
etc.) should be copied into the directory/ies where your device
drivers look for .pk files to translate .dvi files into printed or
displayed output.

If your TeX looks at one directory, where the magnifications and resolutions 
of the pk files are indicated as part of the extension of the filename, then 
you may copy them precisely as they are. If your TeX expects all pk files to 
have the extension simply `.pk' and the magnifications and resolutions are
determined by the name of the subdirectory in which they appear, then you 
will want to copy them into subdirectories named similarly to their current
extensions, and rename them all to have extension `.pk'. For example, if your
TeX looks for a subdirectory named DPI300 for 300dpi pk files, then you will
want to copy all of the files *.300pk into that directory and then rename 
them all to *.pk; also copy *.329pk into DPI329 (or whatever name your TeX 
uses) and then rename them all to *.pk; etc...

The .tfm files from the directory /pub/tex/amsfonts/tfm should be
copied into the directory on your system where your implementation of
TeX looks for .tfm files.

2. Installing the auxiliary files:

There are two sets of files which provide macros necessary for using
AMSFonts 2.2 in TeX. One set is for Plain TeX or AMS-TeX, and one set
is for LaTeX.  If you use Plain TeX or AMS-TeX, then the files in
/pub/tex/amsfonts/plaintex should be placed in the directory (or a
directory in the path) which your implementation of TeX searches for
input files. If you use LaTeX2e, then the files in
/pub/tex/amsfonts/latex should be placed in that directory. 

WARNING: If your version of LaTeX2e is earlier than December 1996, and
if your operating system and TeX implementation both refer to
filenames in a case-sensitive manner, you will need to use the .fd
files in the obsolete subdirectory of the latex directory, instead of
the .fd files in the latex directory. Note that this generally does
not apply to you if you are using DOS/Windows or using Textures
on the Macintosh.  However, if you are using TeX in Unix or using
OzTeX on a Macintosh, this warning does apply to you.

If you are likely to use LaTeX2e as well as Plain TeX or AMS-TeX, then
install the files from both directories where your TeX will find them
for input.

If you use LaTeX 2.09, then we strongly encourage you to upgrade your
installation to LaTeX2e, as this is the current standard for LaTeX
throughout the world, and we do not provide support for use of
AMSFonts in LaTeX 2.09. 

3. The User's Guide:

The `doc' subdirectory (/pub/tex/amsfonts/doc) contains five files which
have filenames beginning with `amsfndoc'. In order to TeX and print
the entire User's Guide, you must first install the fonts.  When you
have completed all of the above installation steps, run the file
`amsfndoc.tex' through TeX. It will input the other four `amsfndoc'
files. The output will be a complete guide to the use of AMSFonts 2.1.
NOTE: Do NOT use AMS-TeX or LaTeX to TeX amsfndoc.tex; simply use
Plain TeX. 

This directory also contains a file called "amsfonts.faq" in which we
will place frequently asked questions about AMSFonts.

The /latex subdirectory of the "doc" directory contains LaTeX .dtx
files containing technical commentary on the source code for the LaTeX
support files in the AMSFonts distribution. Although these .dtx files
are included for reference, most users can ignore them.

4. Other files:

Some PC device drivers have a font table which needs to be updated in order
for the driver to recognize the fonts. For instance, the TeX Preview software
provided by ArborText has a file called `preview.fnt' which contains the names
of all fonts which the Preview program is expected to find, and the effective
resolutions (resolution multiplied by magnification) at which to find them. In
order to use AMSFonts with this, or any other software which uses such a table,
you must enter the names of each of the fonts in the AMSFonts package and the
effective resolutions at which you have them installed.  The file
`amsfonts.lst' in the /pub/tex/amsfonts directory contains a list of all of the
font names and all of the resolutions for the 118dpi and 300dpi distribution.
You may have to alter the format of this file to make it conform to your
driver's needs or to reflect installation of only some of the fonts, or
globally some of the resolutions with different ones (e.g. replace all
magnifications of 300dpi with corresponding magnifications of 240dpi). See the
documentation for your device driver to see what format is required. IF YOUR
DEVICE DRIVER DOES NOT DEPEND ON SUCH A TABLE, THIS FILE IS NOT NECESSARY.

-----------------------------------------------------------------

USE OF THE LATEX `amsfonts' PACKAGE

Version 2.2 of the LaTeX package amsfonts.sty is carefully constructed
to allow it to be used for processing pre-existing documents originally
written for AMS-LaTeX 1.2beta or earlier. This means that documents that
loaded amsfonts.sty through statements such as the following should
continue to work without change.

1.  \documentstyle[amsfonts]{article}

2.  \documentstyle[amstex]{article}

3.  \documentstyle[amssymb]{article}

4.  \documentstyle{amsart}

5.  \documentclass{amsart}

6.  \documentclass{article}
    \usepackage{amsfonts}

7.  \documentclass{article}
    \usepackage{amstex}

8.  \documentclass{article}
    \usepackage{amssymb}

There is an exception, however, for the variants 6 and 7: If your document
was written for AMS-LaTeX 1.2beta, some time in 1994, AND if it uses any
of the symbols

  \square                \Box
  \lozenge               \Diamond
  \vartriangleright      \rhd
  \vartriangleleft       \lhd
  \trianglerighteq       \unrhd
  \trianglelefteq        \unlhd
  \rightsquigarrow       \leadsto
                         \Join

then you may find that those symbol commands now produce `Undefined
control sequence' errors. The easiest way to fix this is to load
the amssymb package, i.e. change variants 6 and 7 to

6a.  \documentclass{article}
     \usepackage{amssymb}

7a.  \documentclass{article}
     \usepackage{amssymb,amstex}

For symbols \Box, etc, you have a choice of either adding the latexsym
package or defining them in terms of the equivalent symbols from the
amssymb package.
