VFTOVP(1)                                               VFTOVP(1)

NAME
       vftovp  - convert virtual font (vf) files to virtual prop-
       erty lists (vpl)

SYNOPSIS
       vftovp  [   -charcode-format=format   ]   [   -verbose   ]
       vf_name[.vf] tfm_name[.tfm] [ vpl_name[.vpl] ]

DESCRIPTION
       This  manual page is not meant to be exhaustive.  The com-
       plete documentation for this version of TeX can  be  found
       in the info file or manual Web2C: A TeX implementation.

       The vftovp program translates a (program-oriented) virtual
       font file and its accompanying TeX font metric file  to  a
       (human-oriented)  property  list  file.  Thus, the virtual
       font can be edited, and its exact  contents  can  be  dis-
       played mnemonically.  It also serves as a VF-file validat-
       ing program; if no error messages  are  given,  the  input
       files are correct.

       The  filenames are extended with the appropriate extension
       if necessary.

OPTIONS
       The argument  format  to  -charcode-format  specifies  how
       character  codes  are output in the VPL file.  By default,
       only letters and digits are output  using  the  C  integer
       code  (i.e.,  in  ASCII);  the others are output in octal.
       (Unless the font's coding scheme starts with TeX  math  sy
       or  TeX math ex, when all are output in octal.)  If format
       is ascii, all character codes that correspond  to  graphic
       characters,  besides  the  left and right parentheses, are
       output in ASCII.  On the other hand, if format  is  octal,
       all character codes are output in octal.

       Without  the  -verbose  option,  vftovp operates silently.
       With it, a banner and progress report are printed on  std-
       out.

ENVIRONMENT
       vftovp  looks  for  vf_name using the environment variable
       VFFONTS.  If that is not set, it uses  the  variable  TEX-
       FONTS.  If that is not set, it uses the system default.

       See tex(1) for the details of the searching.

AUTHORS
       Donald  E.  Knuth  wrote  the program, based in part on an
       idea of David Fuchs, starting with the code for tftopl(1).
       Karl Berry adapted it for compilation with web2c.
