-/*	YWB:  3/13/98

-	You run the program like normal with any file.  If you want to read portals for the

-	file type, you type:  glview -portal filename.gl0 (or whatever).  glview will then

-	try to read in the .prt file filename.prt.

-

-	The portals are shown as white lines superimposed over your image.  You can toggle the 

-	view between showing portals or not by hitting the '2' key.  The '1' key toggles 

-	world polygons.

-

-	The 'b' key toggles blending modes.

-

-	If you don't want to depth buffer the portals, hit 'p'.

-

-    The command line parsing is inelegant but functional.

-

-    I sped up the KB movement and turn speed, too.

+
+	The portals are shown as white lines superimposed over your image.  You can toggle the 
+	view between showing portals or not by hitting the '2' key.  The '1' key toggles

+
+	The 'b' key toggles blending modes.
+
+	If you don't want to depth buffer the portals, hit 'p'.
