One point that Doug hinted at but didn't comment on explicitly: All
other things being equal, it is more efficient to use the `#!' construct.
One minor clarification: the `#!' passes the file name to the shell
specified as an argument, not as the standard input. One argument
is allowed to preceed this, and is whitespace-separated from the shell
path. Thus:
#! /bin/csh -f
will, if at the top of `/bin/frebus', cause the command `frebus' to
behave as if:
/bin/csh -f /bin/frebus
was the actual command.
