+##  Fast hack at a sysctl filesystem.  The path can be either in
+##  dot-style (kern.mbuf.msize) or in slash-style (kern/mbuf/msize).
+##  Hacked as an example by Brian Grayson (bgrayson%netbsd.org@localhost) in Sep 1999.
+for path in $*; do
+  ##  First, change any slashes into dots.
+  path=`echo $path | tr '/' '.'`
+  ##  Now invoke sysctl, and post-process the output to make it
+  ##  friendlier.  In particular:
+  ##    1.  Remove the leading prefix.
+  ##    2.  Remove a now-leading ".", if any.
+  ##    3.  If we are left with " = <val>", strip out the " = " also.
