mgv is a Motif based viewer for PostScript files which uses Ghostscript as the underlying PostScript rendering engine. Limitted PDF support is also supplied.
Executing mgv is very simple:
mgv [switches] [file.ps [...]]
If you mention multiple files on the command line, mgv will attempt to
open each file in its own window so be careful with
"mgv *.ps".
If no initial file is specified, mgv will try and read from the standard
input if it looks like there is something there; see the
Reading From The Standard Input section for details.
The available switches are detailed in the
Command Line Switches section.
You can also use the -help switch for a compact list of available
switches or the -longhelp switch for a more verbose list.
