[comp.lang.postscript] IS there a way to know char sizes outside PostScript ?

I need some information about the character sizes of all PostScript
fonts.  My problem is this has to be known outside PostScript.  Is
there a good way to get this information ?

The only way I could think of right now is to printout the character
sizes and then enter them into a data file (to build a font-width
table).  This involves a lot of tedious typing.  I tried to use the 
_writestring_ command in PostScript, but failed to write the relevent
information into a file.  So if anyone could give me some instruction
about how to read and write files in PostScript, it will be really
appreciated.
