Partial font downloading utility.

SYSTEMS: Unix, VMS, IBM-PC/MS-DOS.
NEEDED:  GhostScript interpreter: GS 2.6.1 (recomended) or GS 3.12

This tool realizes partial downloading of the ATM compatible Type 1 fonts
required in the specified PostScript file.
This tool is combination of 
  - the psfstat.ps PostScript script 
    which collects information about font using 
  - and SubFont program which extracts from source fonts subfonts which
    contains only required characters.

This approach, in comparison with well known DVIPSONE partial font 
downloading facility, has follow advantages:
  1. That can be applied in many systems which generates PostScript output.
     So, psfstat.ps script was tested with:
        a. DVIPS output;
        b. Frame Output;
        c. MS Windows PostScript driver output.
  2. That prepare not only text fonts but also fonts used in inserted
     pictures. 

However, this approach requires a lot of CPU time to complete scanning
of the PostScript file.

==== USING, for example with DVIPS. ====

Tune DVIPS font maps such that ATM compatible Type 1 fonts 
will not be copied into output PostScript file.
So, you must use for font mapping cmfonts.ref file which contains lines like:
   cmr10 cmr10
but not cmfonts.map file which contains lines like:
   cmr10 cmr10 <cmr10.pfb

In correct case, After command 
   dvips -P??? foo
you will have PostScript file without fonts, which you can print by command
   fload foo.ps | lpr
