# genpwd : generate a password with different criteria
# default 16 car with up and low car, symbol and number
# Usage: genpwd [options] [--extracars=<cars>] [--length=<n>] [nb_passwd]
# Options:
# -h, --help Display that help screen
# -s, --nosymbols Exclude symbols
# -n, --nonumbers Exclude numbers
# -u, --noup Exclude uppercase letters
# -l, --nolow Exclude lowercase letters
# -e=<c>, --extracars=<c>
# Add the given caracters to the possible caracter list
# -L=<n>, --length=<n>
# Set length of the password (default is 16)
# -o=<n>, --occurences=<n>
# Set the maximum occurences of a same caracter (default is 2)
# The function is very slow on Windows
