Ah, interesting. I didn't suspect that. Why can't xscreensaver be used by
root?

There are a lot more to clean up then :)

I think it could be related to the references to The Shining book/movie,
but then there's a lot of other screensavers that make references to
potentially copyrighted material:

apple2: Apple ][ look-and-feel
bsod: several operating systems including Apple's and Microsoft's
pacman: Namco's game, including level design
penetrate: Atari's Missile Command
pong: Atari's Pong game
qix: Taito's Qix
boing: Amiga logo
flyingtoasters: After Dark screensaver
glsnake: Rubik's Snake toy
lament: Hellraiser movie
lavalite: Mathmos Lava Lamp
pipes: Windows NT screensaver
rubik: Rubik's Cube toy
sproingies: Gottleib's Q*Bert
starwars: classic Star Wars crawler
superquadrics: Windows screensaver

I'll check the archives. But given the other screensavers listed above
and the fact that Warner doesn't enforce any rights over the screensaver
design, I would include them and wait for a cease-and-desist letter.
Even if copyrighted, I would say it fits the fan art/fair use category
to make a noncomercial screensaver out of the design.

File lists for gl and non-gl screensavers. It prevents problems such as
the current issue of having gl screensaver manpages in the non-gl package.

# Make a pair of lists, of the GL and non-GL executables.
# Do this by parsing the output of a dummy run of "make install"
# in the driver/, hacks/ and hacks/glx/ directories.

list_files() {
    make -s install_prefix=%{buildroot} INSTALL=true "$@"       |

    sed    -e "s!^%{buildroot}!!"                               \
           -e "s!/bin/\.\./!/!"                                 |
    sed    -e 's!\(.*/man/.*\)!\1\*!'                           |
