## This script does the grunt work.  Using information generated by 
## 1vfinst and given in the parameter file vfinst.par, this script 
## will generate TeX files and other scripts to generate the virtual 
## fonts, to create needed directories, and to move files into the 
## proper places.

#< This file contains definitions for the following subroutines:
#>

## What this script expects.
## =========================
## 1. a fresh copy of psfonts.map in the work directory.

# SUBROUTINES AND STUFF ...

require("../vfinst.par"); # system dependent!! Beware!!
require("..${sep}vfinst.lib");
&getTDSplaces if &isTDS; # construct some TDS parameters
##$vfencoding = $vfmapdir unless defined $vfencoding;
$cp = $copy;			# a synonym
$rm = $del;			# another synonym

##$vfencoding = "" if $vfencoding eq $root; # This eliminates strange 
				# double backslash path names in 
				# case you place the enc file in the root

## We begin by extracting font information from the file fonts.lst,
## painstakingly prepared by 1vfinst.  This file begins with column 
## headings (which we ignore) and is followed by lines of the form
##   mbm300 mbmr8a   000 mbur8a.pfb  BulmerMT-Regular
## whose fields are the sortkey, proposed Berry fontname, slant, existing
## font outline name, and long (Adobe or Monotype or ...) font name.
## The matching afm file must have a name formed by stripping the existing
## extension if there is one and appending `.afm'.  Note that slant sometimes
## varies within members of a family, as in Bulmer, with slightly 
## different slants depending on whether the font is regular, bold, 
## or semi.

## The `parseberryname' routine takes a Berry name like "mbmri8a" 
## as argument.

    local($l) = length $scr;
    $berryvars = substr($scr, 4, $l-4-2); # variants
}

## we need to retrieve this information.

    local($name_plus_extensions) = $_[0];
    ## $name_plus_extensions looks like `foo.{pfb,afm}'
