This version of GhostScript supports shared modules dynamically loaded
at run time.

There are currently two modules compiled with this version of
GhostScript, one to support all X11 devices (typically used by gv) and
another to support the svgalib devices. See the .so files in
/usr/lib/ghostscript/<version>/ or /usr/local/lib/ghostscript/<version>/.

There is no configuration needed, just add (or remove) the .so files
to add (or remove) the appropriate devices in GhostScript.
