[Tutor] python equivalent of perl readlink()?

[Bill Campbell]

Is there a python equivalent of the perl readlink() function
(e.g. one that returns the relative path in cases where a command
such as ``ln -s ls /usr/local/bin/gls'' created the link?

Reading the documentation on the various os.path functions, the
only thing I see returns the fully resolved path rather than the
relative one (/usr/local/bin/ls in the case above).
