%description
A modular screen saver and locker for the X Window System.
Highly customizable: allows the use of any program that
can draw on the root window as a display mode.
More than 120 display modes are included in this package.
%{?USE_GL:See also the xscreensaver-gl package, which}
%{?USE_GL:includes optional OpenGL display modes.}

# This is a tricky part...
#
# xscreensaver installs several files that are also installed by the
# "control-center" RPM.  The versions from xscreensaver are better,
# and so should override control-center.  But, the way RPM works,
# if the xscreensaver RPM contained those files, the end user would
# have to "--force" to make the xscreensaver RPM install.  That's
# not something people are used to doing, so that's Bad.
#
# So instead, we rename the files so that they don't conflict with
# the control center.  Then we have a "%post" script that creates
# symbolic links to our files.
