AMSFonts PostScript Fonts (Adobe Type 1 format)

-----------------------------------------------------------------------------
The PostScript Type 1 implementation of the AMSFonts produced by and
previously distributed by Blue Sky Research and Y&Y, Inc. are now freely
available for general use. This has been accomplished through the cooperation
of a consortium of scientific publishers with Blue Sky Research and Y&Y.
Members of this consortium include:

Elsevier Science IBM Corporation Society for Industrial and Applied
Mathematics (SIAM) Springer-Verlag American Mathematical Society (AMS)

In order to assure the authenticity of these fonts, copyright will be held by
the American Mathematical Society. This is not meant to restrict in any way
the legitimate use of the fonts, such as (but not limited to) electronic
distribution of documents containing these fonts, inclusion of these fonts
into other public domain or commercial font collections or computer
applications, use of the outline data to create derivative fonts and/or
faces, etc. However, the AMS does require that the AMS copyright notice be
removed from any derivative versions of the fonts which have been altered in
any way. In addition, to ensure the fidelity of TeX documents using Computer
Modern fonts, Professor Donald Knuth, creator of the Computer Modern faces,
has requested that any alterations which yield different font metrics be
given a different name.

The AMS does not provide technical support or installation assistance beyond
any installation instructions included in this file.  Installation and use of
these fonts may require some technical expertise.  Review this READ.ME file
in its entirety before undertaking an installation.

The fonts are available in Macintosh and PFB (binary Type 1) outline
formats. Users requiring the fonts in PFA form should convert them with the
aid of one of the following tools, available from CTAN:

         -   fonts/utilities/ps2mf/pfb2pfa
         -   fonts/utilities/ps2pk/ps2pk15/misc/pfb2pfa
         -   systems/msdos/4alltex/diskp1/pfb2pfa.zip

The canonical version of the PostScript AMSFonts is located on
the AMS FTP server, ftp.ams.org, at /pub/tex/psfonts/amsfonts.

History

The PostScript versions of the AMSFonts were produced  by Blue Sky Research
of Portland, Oregon, and Y&Y, Inc., of Concord, Massachusetts, who published
the fonts in conjunction with their commercial implementations of the TeX
program.

Character outlines were derived from high-resolution METAFONT-generated
character bitmaps by the ScanLab application from Projective Solutions (Ian
Morrison and Henry Pinkham), applied and corrected by Douglas Henderson of
Blue Sky Research. Character hints were created by software from Y&Y
(Berthold and Blenda Horn), with extensive hand work by Blenda Horn. Font
engineering, production, and packaging were by Douglas Henderson and Berthold
Horn.

Installation Instructions for Unix

1. If your installation conforms to the "TeX Directory Structure" standards

If your installation conforms to the TDS standards, then you will want to
create a subdirectory of /usr/local/lib/texmf/fonts called "ams", and 
give it subdirectories names "tfm" and "type1". Place the files in the
"tfm" subdirectory of this distribution in /usr/local/lib/texmf/fonts/ams/tfm,
and the files in the "pfb" subdirectory of this distribution in
/usr/local/lib/texmf/fonts/ams/type1.

2. If your installation does not conform to TDS standards

Copy the .tfm files in the "tfm" subdirectory of this distribution
into the directory where your implementation of TeX looks for .tfm
files.  Copy the files from the "pfb" sudirectory of this distribution
into the directory where your dvi-to-PostScript printer driver looks
for Adobe Type 1 ("PostScript") font outline files. Please consult the
documentation for your TeX installation and for your printer driver to
determine where to place these files.

3. More information for specific printer drivers

The AMSFonts in Adobe Type 1 format have exactly the same metrics as
corresponding bitmapped AMSFonts, hence the same TFM files are used by TeX.
TeX concerns itself only with metric information --- which is contained 
entirely in the TFM file. The same DVI file is used for AMSFonts in Adobe 
Type 1 format as for corresponding bitmapped AMSFonts in PK format.

The DVI processor (previewer or printer driver), however, has to be able to
deal with fonts in Adobe Type 1 format (referred to as `PostScript' fonts by
some).  How this works is a function of which DVI processor is being used.
Read the manual for your DVI processor.  

By far, the most commonly used DVI-to-PostScript processor used in
Unix is DVIPS. If you are using DVIPS, consult with the system
administrator or whoever installed DVIPS to find out where it looks
for Adobe Type 1 format font files. Copy all of the .pfb files in the
`pfb' subdirectory of this directory into that location.

For use with DVIPS, fonts in Type 1 format have to be listed in the
file `psfonts.map' (typically found in `/usr/lib/tex/ps' or
`/usr/local/lib/texmf/dvips' or something along those lines). If the
fonts have PostScript FontNames different from the TFM file name, then
both TFM file name and PostScript FontName must be mentioned on the
line listing a particular font (see `psfonts.ams' in the `mapfiles'
directory).

DVIPS can be asked to `automatically download' the outline font for
the duration of the print job.  In this case each line added to
`psfonts.map' should end with `<' followed by the file name of the
corresponding PFB file.  DVIPS will typically look for the
outline font files in PFB format in the directory
`/usr/lib/tex/ps' (see `psfonts.amx' or `psfonts.amz' in the
`mapfiles' directory).

AFM files have been provided in the event they are needed for a
particular application.  It is assumed that application instructions
will indicate where these should be installed.
