--enable-subdir=DIR Put the demo programs in a subdirectory of \`bindir',
instead of putting them in bindir itself. You can
specify the name of the subdirectory. For example,
- --exec-prefix=/usr/local/bin --enable-subdir=demos
+ \`--exec-prefix=/usr/local --enable-subdir=demos'
would put xscreensaver in /usr/local/bin/, and would
put the demos in /usr/local/bin/demos/. (If DIR
begins with /, then bindir will not be prepended.)
