How to get a script's directory

[ZeWaren / Erwan Martin]

Hi,
I'm writing scilab scripts (.sci files) on a daily basic.
Theses scripts need to access some files around them, typically graphs.

How can I get the location of the script in a variable, so that I can do 
something like this?:
    cpath=get_script_path();
    graph=load_graph(cpath+'some_graph.graph');
I need to be able to execute my scripts on different computers in 
different places on different operating systems.
I know that I can get scilab's current working directory using pwd() and 
change it using cd(...), but this doesn't solve my problem.

Thanks for any response.
