+=head2 format_date
+
+ $formatteddate = format_date($date);
+
+Takes a date, from mysql and returns it in the format specified by the library
+This is less flexible than C4::Date::format_date, which can handle dates of many formats
+if you need that flexibility use C4::Date, if you are just using it to format the output from mysql as
+in circulation.pl use this one, it is much faster.
