Pltfilter

The main source files are in the top directory.  Additional source files
are in the directory tree libuti.  A test directory has a test file to
exercise pltfilter.

Customization:

The pltfilter package has been run on Decstations under Ultrix using the DEC
Fortran compiler.  Recently it was ported to a Sun.  There the package has
had less testing, particularly for plot devices other than PostScript.

An earlier version of this program ran under VMS.  A collection of VMS
replacements for some of the routines from that earlier version is in
the directory vms.

Routines which are specific to Unix are confined to the following:
  pfgetp.f
  libuti/file/*.f
  libuti/plot/devices/*.f
  libuti/utility/*.f
  
Building pltfilter on Unix:

For Unix systems, use the Makefile to create an executable called pltfilter.
  % make

Testing:

The test directory has a Unix script for running a number of sample plots.
This can run as
  % ./tpltfilter
This directory also contains sample PostScript outputs.

Documentation:

The headers for the files pltfilter.f, plinit.f  and plotyx.f document the
program.  These headers are available separately as pltfilter.doc.
