		PS2PK installation summary
		--------------------------
			(March 1995)

For the version which works with Karl Berry's path searching, 
run configure in this directory and use the Makefile which is
generated.  Otherwise follow the instructions below
There needs to be a fully configured kpathsea directory
at the same level as this.

Special versions of MakeTeXPK and texmf.cnf are provided
These are needed for the proper running of this version
of ps2pk.

		       (January 1994)

The ./src directory contains the sources to build the following programs:
  - ps2pk	a program to build PK fonts from PostScript type1 fonts
  - pk2bm	a program that allows to look at a PK character.
 		
To install and use these programs follow next steps:
 1) - Go to the ./src directory.  

      Select a Makefile.xxx
	 System    xxx
	 ------------------------------------------------------------
	 UNIX      unx  A universal UNIX makefile using gcc.
	                This makefile is tailored to BSD like UNIX-es. On
	                SYS5 UNIX systems some small changes may be
	                necessary.

	 MSDOS     bcc  Borland C 3.1. The programs compile but ps2pk.exe
                        does not run (program does not fit in 640k!).

		   djg  Delorie's port of gcc. The programs compile and run
			on 386 compatible machines only. Ready compiled
			versions are available that run on MSDOS or
			MSWindows (386 with or without a coprocessor needed).

		   emx  Eberhardt Mattes port of GCC with an extender that
			can be used on MSDOS and OS2. Only 386.

		   wat  For the Watcom/386 compiler.

      Copy the selected Makefile.xxx to Makefile.

      Edit the Makefile to adapt the T1INPUTS path and the bin and man
      directories.
      
    - Do a `make'. This will create the tools above.
      The master Makefile calls the appropriate Makefile in the ./type1
      directory to install a type1 library. If your compiler has problems
      in compiling this library you possibly have to adapt that
      makefile to your needs.

    - Do a `make install'.
      This will install the above programs.

    - Do a `make install.man'.
      This will install manual pages for the above programs.

 2) Testing ps2pk from ./src directory. 
    The directory ../Utopia contains the Utopia-Regular font donated by
    Adobe. To make from this type1 font a PKfile next steps are needed:
         setenv T1INPUTS ../Utopia		(C-shell)
         ps2pk -v -X300 Utopia-Regular.pfa      (long)
     or: ps2pk -v Utopia-Regular.pfa            (short using defaults)

    This will create the Utopia-Regular10.300pk font with the default
    AdobeStandard characters derived from ../Utopia/Utopia-Regular.afm.
    (The -v flag will show what the program is doing and which character
    codes are generated.)

    To see how for example the `Q' is rendered by ps2pk (using the IBM
    type1 rendering software) you can use:
         pk2bm -bcQ Utopia-Regular10.300pk

    MSDOS has problems with such long names as Utopia-Regular10.300pk. That
    is the reason that dvips uses abreviations for the PostScript names. The
    short name for TeX's virtual font needed to use Utopia-Regular is `putr'.
    The short name for its raw counterpart is `rputr'. To generate rputr.pk 
    the equivalent of Utopia-Regular10.300pk in directory 300dpi you have to 
    use (on MSDOS):
         ps2pk -v Utopia-Regular 300dpi\rputr.pk
    
    Ps2pk has some extra options. All options are explained in the manual page
    (man/ps2pk.1). Here are the most important:
       -X<xres>	     the desired X-resolution (ex: 300, 329, 360, 432, etc)
       -E<expansion> the factor to expand a font
       -S<slant>     to get a slanted font.
    
 3) Using the ps2pk rendered fonts with xdvi.
    The main reason why ps2pk is written is to use the PK fonts for
    previewing a (La)TeX document that uses PostScript fonts. But some
    people use the PKfonts instead of the original type1 fonts that are
    available in the printer because they consume less virtual memory
    or because the printing goes faster.

    To use putr the TeX version of Utopia-Regular in xdvi you will need:
       - the latest version of xdvi (supporting virtual fonts)
       - putr.tfm and putr.vf (the virtual TeX-face of Utopia-Regular)
       - rputr.tfm and rputr.300pk (the raw TeX-face of Utopia-Regular)
       - testfont.tex (a plain TeX source to test the font).
    
    We have explained how to make rputr.300pk from Utopia-Regular. How do
    we generate rputr.tfm, putr.vf and putr.tfm? The first TFM file can be
    generated with afm2tfm, coming with dvips, in the following way:
       - afm2tfm Utopia/Utopia-Regular.afm -v putr.vpl rputr.tfm
    
    The TFM/VF files for putr can be generated from the virtual property
    list file (VPL) with vptovf:  
       - vptovf putr.vpl putr.vf putr.tfm
    
    Now we have to verify that xdvi can find all these VF and PK fonts
    by adding the current directory to the PATH's used for locating them:
       - XDVIVFS	(path for VF files)
       - XDVIFONTS	(path for PK files)
    
    Now we are ready to test Utopia-Regular:
       - tex testfont
       
         If TeX asks for a font enter `putr' and when asked for a test
         enter `\bigtest\bye' and you will get a testfont.dvi file.
         (Testfont.tex is distributed with every TeX version.)

       - xdvi testfont
       
         If everything is OK you should see Utopia!
    
    (You can try another testfont with `rputr' instead of `putr'. Explain
    the differences!)

 4) Using Utopia-Regular with dvips.
    Before you can run dvips to generate the PostScript output that can
    be printed you have to make the font available to dvips by adding a
    line to psfonts.map (normally located in /usr/local/lib/tex/ps).
    This line tells dvips if a font is resident (available in the
    printer) and if not how to download it. For rputr we need to add 
    next line in psfonts.map (the new version of afm2tfm will show this
    line on the standard output):
       rputr Utopia-Regular
    
    and to copy or to move Utopia-Regular to /usr/local/lib/tex/ps so
    that it will be downloaded (added to the PostScript output).
       dvips testfont
    
    If you have GhostScript, and your dvips is installed so that it does
    not send the output immediately to the printer, you can check 
    testfont.ps behind your X-display with:
       gs testfont.ps

 5) Using rputr.300pk with dvips.
    You have to remove the line you have added to psfonts.map. Then
    dvips will try to find a PK-font instead of the type1 font.
    
 6) Automatic font generation with MakeTeXPK.

    If you are interested in automatically generating PK fonts from
    either METAFONT and/or type1 sources you may want to install the
    MTPK package. This package provides a perl script that allows
    DVI drivers to generate missing PK sizes in a platform independant
    way. See ftp.urc.tue.nl:pub/tex/MTPK??.gtz and the MTPK??.README
    file for more information (under development).

 7) Although ps2pk is set up for AdobeStandardEncoding, the default used 
    by current versions of dvips, it will also accept other PostScript
    and TeX encodings. An interesting alternative for TeX users is the new
    TUG 8bits font standard (see: TUGboat #10 vol. 4 1990). This standard
    is a superset of ISOLatin1 with many accented characters. The PostScript
    encoding used by this new font is contained in etc/EC.enc. In order to
    use it you will need afm2tfm version 7.0 (distributed with dvips5485++).

    [Here you should read two danger bends!! Next in small letters . . .

    As an example how an encoding scheme other than Adobe Standard can
    be used we show how you can use the Utopia-Regular font as an
    extended Computer Modern font. We use this encoding scheme both on
    the TeX input side (let us call that internal encoding) and on the
    TeX output side (we will call that external encoding). It is clear
    that we can not use the plain macros that are still based on
    oldstyle 7bits internal encodings.  But we can use NFSS-DC a new
    font selection scheme based on DC encodings. The DC encoding is a
    preliminar version of the EC encoding.
    
    How do we generate the appropriate TFM, VF and PK files?
      rputr.300pk:
         setenv T1INPUTS Utopia			(C-shell)
         ps2pk -e etc/EC.enc Utopia-Regular rputr.300pk
      rputr.tfm and putr.vpl:
         afm2tfm Utopia/Utopia-Regular.afm -p etc/EC.enc -v putr.vpl rputr.tfm
      putr.vf putr.tfm:
         vptovf putr.vpl putr.vf putr.tfm
    
    How do we use it?
      psfonts.map (add line):
         rputr Utopia-Regular " ECEncoding ReEncodeFont " <EC.enc
      $TEXCONFIG:
         install here Utopia-Regular and EC.enc
      testfont.tex (tex-nfss-dc is a special plain TeX version):
         tex-nfss-dc testfont (choose `putr' and '\bigtest\bye')
         xdvi testfont
         dvips testfont.
    
    . . .End of dangerous stuff and the small letters]
