Using PWD

[Arthur Schwarz]

I'm trying to find the directory of an executing bash script and am having
very limited success. For example(s):

1. <path>/script.sh
2. source <path>/script.sh
3. bash <path>/script.sh

I can find the correct <path> only for the first example (dirname $0). PWD
(of course) only works when <path> == ./. The other two cases I can't seem
to get to work. Any idea how to get the <path> in examples 2 and 3?
