   Furthermore, csh(1) automatically sets $path when you perform the command
"setenv $PATH".  As far as I can see, the major difference between $PATH and
$path is that the latter is really only a part of your csh(1) operating
environment.  $PATH is the variable that is understood inside of all programs,
being imported through the environment pointer and available through the
getenv(3) call.
