-   Template for a setuid program that calls a script.
-
-   The script should be in an unwritable directory and should itself
-   be unwritable.  In fact all parent directories up to the root
-   should be unwritable.  The script must not be setuid, that's what
-   this program is for.
-
-   This is a template program.  You need to fill in the name of the
-   script that must be executed.  This is done by changing the
-   definition of FULL_PATH below.
-
-   There are also some rules that should be adhered to when writing
-   the script itself.
-
-   The first and most important rule is to never, ever trust that the
-   user of the program will behave properly.  Program defensively.
-   Check your arguments for reasonableness.  If the user is allowed to
-   create files, check the names of the files.  If the program depends
-   on argv[0] for the action it should perform, check it.
-
-   Assuming the script is a Bourne shell script, the first line of the
-   script should be
-    #!/bin/sh -
-   The - is important, don't omit it.  If you're using esh, the first
-   line should be
-    #!/usr/local/bin/esh -f
-   and for ksh, the first line should be
-    #!/usr/local/bin/ksh -p
-   The script should then set the variable IFS to the string
-   consisting of <space>, <tab>, and <newline>.  After this (*not*
-   before!), the PATH variable should be set to a reasonable value and
-   exported.  Do not expect the PATH to have a reasonable value, so do
-   not trust the old value of PATH.  You should then set the umask of
-   the program by calling
-    umask 077 # or 022 if you want the files to be readable
-   If you plan to change directories, you should either unset CDPATH
-   or set it to a good value.  Setting CDPATH to just ``.'' (dot) is a
-   good idea.
-   If, for some reason, you want to use csh, the first line should be
-    #!/bin/csh -fb
-   You should then set the path variable to something reasonable,
-   without trusting the inherited path.  Here too, you should set the
-   umask using the command
-    umask 077 # or 022 if you want the files to be readable

-   The other changes to the environment are, strictly speaking, not
