### First try to get gv, then ghostview,

### exists. Do not use "which" command here.
#%// BK 25-Sep-2001 which seems more robust than -x...
#%// BK 16-Jun-2003 but which is extremely slow on SUN...
#%// BK 16-Jun-2003 therefore simply use "ghostview" and assumes
#%// BK 16-Jun-2003 everybody has that, or is smart enough to change it here

### simply make sure it is known as "ghostview" using a link.
