Extract inputs/outputs and required parameters from script?

[Bertrand Dechoux <de...@gmail.com>]

Hi,

The command line and its output explain what are the required parameters
and the inputs/outputs of a script. I was wondering : is there a simple way
to extract them automatically from the script?

For the parameters, I could parse the file with my own logic, inputs/ouputs
should also be doable but might be harder. However if there is a
proven/safer way to do it, that would be best.

Has anyone experience on this subject?

Regards
