-
-
-**/ 
-
-/** @defgroup date_alg Date Algorithms / Generators
-  Date algorithms or generators are tools for generating other dates or
-  schedules of dates.  A generator function starts with some part of a
-  date such as a month and day and is supplied another part to then
-  generate a final date.
-
-**/

-/** @defgroup date_format Date Formatting
-  The functions on these page are some of the key formatting functions
-  for dates.  
-**/ 
-
-
-//File doesn't have a current purpose except to generate docs
-//and keep it changeable without recompiles
-/*! @example days_alive.cpp 
-  Calculate the number of days you have been living using durations and dates.
-*/
-/*! @example days_till_new_year.cpp 
-  Calculate the number of days till new years
-*/
-/*! @example print_month.cpp 
-  Simple utility to print out days of the month with the days of a month.  Demontstrates date iteration (date_time::date_itr). 
-*/
-/*! @example localization.cpp
-  An example showing localized stream-based I/O.
-*/
-/*! @example dates_as_strings.cpp 
-  Various parsing and output of strings (mostly supported for 
-  compilers that do not support localized streams).
-*/
-/*! @example period_calc.cpp 
-  Calculates if a date is in an 'irregular' collection of periods using
-  period calculation functions.
-*/
-/*! @example print_holidays.cpp
-  This is an example of using functors to define a holiday schedule
- */
-/*! @example localization.cpp
-  Demonstrates the use of facets to localize date output for Gregorian dates.
