 HINTS:
 ======
 
-If your interpreter does not look at the PATH to determine the full name of the
-program, you need to invoke a wrapper-script (like the following for java) first:
+If you want to pass special arguments to your interpreter, you can
+write a wrapper script for it.
 
-#!/bin/sh
-FOO=`which $1` || exit 1
-shift
-/usr/local/bin/java $FOO ${1+$@}
+Your interpreter should NOT look in the PATH for the filename; the
+kernel passes it the full filename to use.  Using the PATH can cause
+unexpected behaviour and be a security hazard.
