Is it just me, or is the $result in $result= GetOptions (...option-descriptions...); of perlman:Getopt::Long not described?

I´m searching of a way to automatically show usage information, if the user happens to give in wrong commandline options. I assumed (from experiments), that $result is the number of successfully parsed options and undef in case of a error. It is not :-(

Very (seems useless) behaviour of $result:

undef if one false input
1 if one ok input
undef if two ok inputs

??? enlighten me please

Ciao
