Command-line option equiv of PYTHONPATH

[Rajesh]

Hi,

The '-I<path>' option adds the path to the list of directories that
contains modules that can be included in a script. I can use it as "#!/
usr/bin/perl -I<path_to_my_modules>" thereby not asking the user of
the script to set the <path_to_my_modules> in their environment.

Is there any equivalent command-line option to the python binary or a
command-line version of PYTHONPATH?
