How to add the current dir to sys.path when calling a python file?

[Peng Yu]

Hi,

man python says "If a script  argument  is  given,  the directory
containing the script is inserted in the path in front of $PYTHONPATH.
The search path can be manipulated from  within a Python program as
the variable sys.path." Instead I want to have the current directory
inserted to the front of $PYTHONPATH without changing anything the
script. Is there a way to do so?
