# ex2: advanced use of Config::Validator with Getopt::Long
#
# compared to ex1:
# - --debug can be repeated (Getopt::Long's "+") and is aliased to -d
# - named schemas are used to avoid schema duplication
# - the configuration hash is treeified
#
# $ perl ex2.pl -h
# $ perl ex2.pl -d -d --src-host foo --dst-host bar --dst-port 80
#
