yes it is. one thing that isn't obvious however, is that in addition
to creating your PostScript files (by issuing REPORT commands) you
also need to create a file that looks like the following.
i'm no expert on the Distiller command line options, i just found
this documented in the Adobe help and copied the command line.
the second step mentioned above,
is to distill this file. the filename you give this file determines
the root filename of the resulting pdf file.
