+# These flags are normally set in config.h which is generated by the autoconf
+# script as the initial step of the xscreensaver build process. The flags
+# enable/disable code in the various screenhack library files. When compiling
+# elsewhere than FreeBSD, these flags will likely need to be changed.  If

+# Since we're only building standalone hacks (i.e. building outside the
