 We also support future dates and times::
 
- present = datetime.now()
- past = present - timedelta( 492, 58711, 45 ) # days, secs, ms
- future = present + timedelta( 2, 12447, 963 ) # days, secs, ms
+ PRESENT = datetime.now()
+ PAST = present - timedelta( 492, 58711, 45 ) # days, secs, ms
+ FUTURE = present + timedelta( 2, 12447, 963 ) # days, secs, ms
 
- print 'Shutdown in ' + human( future )
+ print human( FUTURE )
 
 Now we will document how to use delta2human and delta2dict::
 
- # pretend we already have a timedelta object
-
  # subtract two datetime objects for a timedelta object
- d2 = datetime.now()
- delta = d2 - d1
+ delta = PRESENT - db_date
 
  # display a human readable timedelta from a timedelta 
- print 'Created ' + delta2human( delta ) + ' ago.'
+ print 'Created ' + delta2human( delta )
 
  # create a dictionary out of the timedelta
- delta_dict = delta2dict( delta )
- print delta_dict
+ print delta2dict( delta )
+
+Example format_past and format_future keyword arguments::
+
+ output1 = human( PAST,
+   format_past = 'titanic sunk {0} ago',
+   format_future = 'titanic will sink in {0} from now'
+ )
+
+ output2 = human( FUTURE,
+   format_past = 'titanic sunk {0} ago',
+   format_future = 'titanic will sink in {0} from now'
+ )
+
+ print output1
+ # titanic sunk 1 year, 127 days ago
+ print output2
+ # titanic will sink in 2 days, 3 hours from now
