+# Script to create device nodes for SMART array controllers
+# Usage:
+#	mkdev.ida [num controllers] [num log volumes] [num partitions]
+#
+# With no arguments, the script assumes 1 controller, 16 logical volumes,
+# and 16 partitions/volume, which is adequate for most configurations.
+#
+# If you had 5 controllers and were planning on no more than 4 logical volumes
+# each, using a maximum of 8 partitions per volume, you could say:
+#
+# mkdev.ida 5 4 8
+#
+# Of course, this has no real benefit over "mkdev.ida 5" except that it
+# doesn't create so many device nodes in /dev/ida.
