+# Scheduler options:
+#
+# Specifying one of SCHED_4BSD or SCHED_ULE is manditory.  These options
+# select which scheduler is compiled in.
+#
+# SCHED_4BSD is the historical, proven, BSD scheduler.  It has a global run
+# queue and no cpu affinity which makes it suboptimal for SMP.  It has very
+# good interactivity and priority selection.
+#
+# SCHED_ULE is a new experimental scheduler that has been designed for SMP
+# although it will work just fine on UP.  Users of this scheduler should
+# expect some hicups and be prepaired to provide feedback.
