 * dclock -- program to demonstrate how to use the digital-clock widget.
 * To specify a date, the date format is a string of characters.  If a
 * character in the string is a %-sign, the next character is examined
 * and a value is inserted into the string.  Example:
 *    dclock -date "Today is %W"
 * The date string will print "Today is" and then the %W will be replaced
 * by the current weekday name.  The parameters are:
 *    %W	full weekday name
 *    %w	three-char weekday name (sun, mon, tue, wed...)
 *    %M	full month name
 *    %m        three-char abbreviation for that month (jan, feb, mar...)
 *    %d	The date (numerical number of the month)
 *    %Y	full year (4 digits)
 *    %y	2-digit year number
 *
 * To specify seconds to be displayed, use "-seconds" or use the resource
 * manager: *Dclock.seconds: on
