The /usr/lib/perl5/getopts.pl is broken: it won't take more than one option with an argument. More precisely: for Getopts('abcde:fghij'), only -e will care about its argument, not -a, -b, -c or -d. The previous version had not this problem. Here is the old one:
Jean, Je crois que c'est l'ancienne qui avait un pb. Il faut sans doute ecrire Getopts('a:b:c:d:e:fghij'); A ce propos, Getopts::Long est tres bien pour les options longues et courtes. Yves.
