Although ptp handles precise exceptions but it doesn't show that
e.g.
ptp=PTP('w3af')
ptp.parse('some/random/non-existing/directory')

Below error is shown
Traceback (most recent call last): File "testing.py", line 3, in <module> c = ptp.parse('/root/Desktop/w3af_repo') File "/root/Desktop/ptp/ptp/ptp.py", line 121, in parse raise NotSupportedToolError('This tool is not supported by PTP.') ptp.libptp.exceptions.NotSupportedToolError: This tool is not supported by PTP.

while it should display why the error occurred like above it should show directory doesn't exists or something related to it, helps in correcting error for user itself.
