                    [-v] [-V] [-?]

    Where:
           -l        = Generate an HTML link for each day of the month.
           -u URLPRE = Generate an HTML link for each day of the month
                       and associate a URL prefix with each link.
           -m MONTH  = Month number to generate calendar (1-12).
           -y YEAR   = 4 digit year to generate calendar.
           -Y        = Generate calendar for an entire year.
           -v        = Verbose mode.
