how to capture command line parameters after source
===

I am running linux 2.6. On bash shell, i would like to source a file. If i am in the current directory as the source file, then i can do 


    source abc.sh

But if i am on some other folder, i would so 

    source /path-to/abc.sh

I would like to capture whatever is typed after the command source on the command line in my script, So, for example, i want access to "abc.sh" and in the latter case, i want access to "/path-to/abc.sh" inside abc.sh

Thank you
