No. I am looking for a way to catch the options the script really knows
nothing about. To be more concrete: the configure script of the brltty
project uses an option called -with-braille-drivers=. For the moment,
when configure is called with the mis-spelled
-with-braile-drivers=something (one l instead of two ls), the user is
not warned. We would like to detect the incorrect options and to report
them. Is that possible ?
Thanks,
Sébastien.
