+=head1 NAME
+
+DateTime::Duration::Fuzzy -- express dates as fuzzy human-friendly strings
+
+=head1 SYNOPSIS
+
+ use DateTime::Duration::Fuzzy qw(time_ago);
+ use DateTime;
+
+ my $now = DateTime->new(
+    year => 2010, month => 12, day => 12,
+    hour => 19, minute => 59,
+ );
+ my $then = DateTime->new(
+    year => 2010, month => 12, day => 12,
+    hour => 15,
+ );
+ print time_ago($then, $now);
+ # outputs 'several hours ago'
+
+ print time_ago($then);
+ # $now taken from C<time> function
+
+=head1 DESCRIPTION
+
+DateTime::Duration::Fuzzy is inspired from the timeAgo jQuery module
+L<http://timeago.yarp.com/>.
+
+It takes two DateTime objects -- first one representing a moment in the past
+and second optional one representine the present, and returns a human-friendly
+fuzzy expression of the time gone.
+
+=head2 functions
+
+=over 4
+
+=item time_ago($then, $now)
+
+The only exportable function.
+
+First obligatory parameter is a DateTime object.
+
+Second optional parameter is also a DateTime object.
+If it's not provided, then I<now> as the C<time> function returns is
+substituted.
+
+Returns a string expression of the interval between the two DateTime
+objects, like C<several hours ago>, C<yesterday> or <last century>.
+
+=back
+
+=head2 performance
+
+On 64bit machines, it is asvisable to 'use integer', which makes
+the calculations faster. You can turn this on by setting the
+C<ARCH_64BIT> environmental variable to a true value.
+
+If you do this on a 32bit machine, you will get wrong results for
+intervals starting with "several decades ago".
