Path problem

[Binu K S]

Hi Lars,

sys.path[0] will contain the path to the script.

>From the sys module documentation:
"As initialized upon program startup, the first item of this list,
path[0], is the directory containing the script that was used to
invoke the Python interpreter. If the script directory is not
available (e.g. if the interpreter is invoked interactively or if the
script is read from standard input), path[0] is the empty string,
which directs Python to search modules in the current directory first.
Notice that the script directory is inserted before the entries
inserted as a result of PYTHONPATH."
