 # Code common to scripts that need to load a kernel module
 # if it isn't in the kernel yet. Syntax:
-#   load_kld [-e regexp] [-m modname] filename
+#   load_kld [-e regex] [-m module] file
 # where -e or -m chooses the way to check if the module
 # is already loaded:
-#   regexp is egrep'd in the output from `kldstat -v',
-#   modname is passed to `kldstat -m'.
-# The default way is as though `-m filename' were specified.
