.SH NAME
fload \- Type 1 font downloading utility.
.SH SYNOPSIS
.B fload [-p font-set] <source-PS-file> [<output-PS-file>]

.SH DESCRIPTION
.B Fload 
is C-shell script that 
parses (via GhostScript with 
.I psfstat.ps 
script) legal PostScript file, determines characters and fonts which
are required but not preloaded into file and then loads required fonts
.I partially 
(by using 
.I SubFont
program). Source will be also copied into output streem.
If name of output file is missed, script will write into standard output.
So, anyone can print file by command:
   fload foo.ps | lpr
.SH OPTIONS
.TP 12
.B -p font-set
This option selects font-set which is in your printer.
In standard configuration, only two font sets are distributed:
   Standard (default)
   35
 However, adding of the new font sets is trivial procedure.
In this reason 
.B fload
called without parameters will shows list of available font sets.
.SH REMARK
To make partial font downloading procedure successfully 
fonts intended to be downloaded partially must not be included 
into <source-PS-file>.
.SH ERRORS
Several errors can accure in this process:
   1. Source file is absent.
   2. Can't write destination file(s)
   3. Invalid PostScript file or required font is not accessible. 
In this case one can examine
.I *.flog
file which contains protocol of the source parsing by GhostScript.
.SH LIMITATIONS
This software was tested with PS output of
   the DVIPS program
   the FrameBuilder (Unix)
   MS Windows PostScript driver.
  
There is no guarantee that any PostScript file will be processed successfully
because of high flexibility of the PostScript language.

This software was tested with several fonts and accounts such kinds of
ATM compatible Type 1 fonts as hybrid fonts, Multiple master fonts
and fonts with shareable set of the CharStrings.
However, every new font must be tested that it will be correctly downloaded
partially. Note, that Multiple master fonts can be downloaded correctly only 
with GhostScript version 3.12 and higher. 
However, this version have a lot of bugs 
that result in crashing of GS interpreter.
