Taint mode

There are lots of problems with using taint mode, and these days there are much better and nicer ways to validate user-supplied data and prevent environment poisoning than using -T. I'd suggest rewording the sections mentioning -T.

thanks,
I'm very ignorant about this..

the relevant part Is there only because I acted in a wrong way during the creation of the module and the relative online repository.

I realized it after many commits and was too late to revert.

Security can be whole chapter per se, but I have no knoweledge about it
