+How to use
+==================
+
+Import ago and create a timedelta object::
+
+ from ago import delta2dict, human
+ 
+ from datetime import datetime
+
+ # pretend this was stored in database
+ d1 = datetime( 
+   year = 2010, 
+   month=5, 
+   day=4, 
+   hour=6, 
+   minute=54, 
+   second=33, 
+   microsecond=4000
+  )
+
+ # this is right now
+ d2 = datetime.now()
+
+ # subtract the two for a timedelta object
+ delta = d2 - d1
+
+ # create a dictionary out of the timedelta
+ # not needed but accessable
+ delta_dict = delta2dict( delta )
+ print delta_dict
+
+ # display a human readable timedelta 
+ print 'Created ' + human( delta ) + ' ago.'
+
+ # optionally pass a precision
+ print 'Created ' + human( delta, 3 ) + ' ago.'
+ print 'Created ' + human( delta, 6 ) + ' ago.'
