AMSFonts 2.1 READ.ME June 1991 This is a documentation file to accompany the AMSFonts 2.1 distribution. Copy all of the files in this directory (/ams/amsfonts) and all of its subdirectories into a corresponding directory tree on your system. ALSO, copy all of the .tfm files for AMSFonts 2.1 from the tfm-files subdirectory of the ams directory on this archive (/ams/tfm-files). Read the section below, "Installing AMSFonts 2.1 on your system," for instructions for correct installation. NOTE: MANY OF THE TFM FILES FOR AMSFONTS HAVE CHANGED FROM VERSION 2.0. Line and page breaks may be affected by these changes. Therefore, we suggest that you regenerate any DVI files which refer to these fonts, after version 2.1 has been installed. ------------------------------------------------------------------ WHAT CHANGES WERE MADE IN VERSION 2.1, AND WHY SHOULD EVERYONE UPGRADE? The changes which you will most readily notice are: 1. All of the Euler Bold are more bold and extended. In previous releases, eufb was difficult to distinguish from eufm. Now they are more distinguishable. 2. The Euler fonts in sizes smaller than 10 point were beefed up a bit so that they stand out more when used in subscripts and superscripts with 10 point text. 3. The Metafont code for Blackboard Bold was changed so that these characters are much improved at low resolutions. Blackboard Bold characters on your screen or dot-matrix printer will no longer be ugly and unrecognizable. 4. There was a bug in the MSAM fonts which caused them to have different TFM files when generated by Metafont at different resolutions. This led to different TFMs for the same fonts in different locations. Now there is one TFM which will be consistent everywhere (everywhere that version 2.1 has been installed, that is). 5. A few other changes were made which are less noticeable. A change in the code for EUEX eliminated a Metafont error with the 240dpi mode. A Metafont error which sometimes appeared in the Counter-clockwise Arrow was eliminated. Slight changes to some parameters in CMEX9 made it compatible with a previously existing version. The reason everyone should upgrade is simple: In order to solve the problems which existed in version 2.0, the metrics of some of the fonts were changed. This means that the TFM files are different, which means that TeX will produce different line and page breaks. If everyone upgrades to the new version, then the portability of TeX, one of its greatest assets, will remain intact. If you continue to use an old version of these fonts, then your output files may not be portable to other sites. So, PLEASE encourage all of your friends and colleagues to upgrade to AMSFonts 2.1 to avoid confusion and errors. ----------------------------------------------------------------- INSTALLING AMSFonts 2.1 ON YOUR SYSTEM The other files in this directory (amssym.def, amssym.tex, and cyracc.def) should be copied into the directory on your system where your implementation of TeX looks for input files. The files from the appropriate subdirectory of the pk-files subdirectory of this directory (/ams/amsfonts/pk-files/dpi118 for 118dpi fonts, /ams/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 tfm-files directory of the ams subdirectory on this archive (/ams/tfm-files) should be copied into the directory on your system where your implementation of TeX looks for .tfm files. The `doc' subdirectory (/ams/amsfonts/doc) contains four files, all of which have filenames beginning with `userdoc'. When you have completed all of the above steps, run the file `userdoc.tex' through TeX. It will input the other three files. The output will be a complete guide to the use of AMSFonts 2.1. NOTE: Do NOT use AMS-TeX to TeX userdoc.tex; simply use Plain TeX. The `amsfonts.lst' file (for users of IBM-compatible PCs): 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 /ams/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. ----------------------------------------- Questions concerning the use of AMSFonts may be directed to: Technical Support Group American Mathematical Society 201 Charles Street P.O.
