 NAME     
 SYNOPSIS     
 DESCRIPTION     
 |  |  |  | Cal prints a calendar. Month is either a number from 1 to 12,
    a lower case month name, or a lower case three-letter prefix of
    a month name. Year can be between 1 and 9999. If either month
    or year is omitted, the current month or year is used. If only
    one argument is given, and it is a number larger than 12, a calendar
    for all twelve months of the given
    year is produced; otherwise a calendar for just one month is printed.
    The calendar produced is that for England and her colonies.

 BUGS     
 |  |  |  | The year is always considered to start in January even though
    this is historically naive. 
    
    
    Beware that cal 90 refers to the early Christian era, not the
    20th century.
