Your PATH does not include the current working directory, if you do not add
it there.  For instance, on my machine I can see that:

	% echo $PATH
	/sbin:/bin:{lots of dirs trimmed}:~/bin

But nowhere on the path can one find the `.' directory.  You can always add
the directory to your path, by adding to your .cshrc the following:

	set path = ( $path . )

But this is not a recommended way of solving the problem, since it creates
various security issues, when you do it for the superuser.  Just think of the
good ol' trojan called /tmp/mroe and the following commands:

	# cd /tmp
	# ls -l | mroe

Ciao,
Giorgos.
