-! Any program which can draw on the root window will work as a screensaver.
-! The following resource enumerates them.
-!
-! Programs are separated by newlines (specified in resource files with \n).
-! Lines may be continued with a lone \ at the end of the line.
-!
-! Each line is an `sh' command.
-!
-! If the first (non-blank) character on the line is "-", then that means
-! that this command is disabled: it's still in the list, but it won't ever
-! be used. (This is just to make it easy to disable and then re-enable
-! them later.)
-!
-! If the first word on the line is the name of a visual followed by a
-! colon, then that visual will be used for the program, if it is available.
-! If no such visual is available, then the program will be skipped. In
-! this way, you can specify that you want certain programs to run only
-! on color screens, and others only on mono screens, by making use of the
-! magic visual names "color" and "mono". Likewise, if some hacks prefer
-! colormaps, but others prefer 24-bit windows, that also can be arranged
-! (in this case, by using "PseudoColor:" versus "TrueColor:".)
-!
-! Some of the screenhacks are written using OpenGL. OpenGL programs are
-! a bit different than normal X programs, in that they prefer visuals that
-! are *half* as deep as the screen. You can tell xscreensaver to select a
-! good visual for a GL program by using the magic visual name "GL".
