2005-12-11 rekkanoryo <rekkanoryo@users.sourceforge.net>

  * Fixed compiler warnings about no newline at the end of timespan.hpp

  * Fixed bug in get_date() where the function had no explicit return value.

  * Fixed compiler warning in calc_days_between() about unused variable.

version 2.1 -  June 16, 2005 :
==============================
  * Fixed config.hpp for Windows to properly reflect version number.

  * Moved constants from timespan.cpp to constants.hpp to facilitate the
    creation of GUIs.

  * Moved args_parse_for_flags() and args_parse_for_ops() prototypes to
    args_parse_driver().

  * Moved args_parse_driver() prototype to main().

  * Created args_parse_epoch(), args_parse_now(), and args_parse_between().

  * Changed most of the output code.

  * Removed struct File.  It is no longer needed.

  * Updated mantimespan.html.

  * Added the ability to subtract time to the "now" operation and prevented
    subtracting values that are too large.

  * Added the ability to use "epoch" and "now" alone in the middle of a
    command line.
    
  * Added the ability to use "epoch" and "now" as keywords in the "between"
    operation.  "epoch" and "now" can be used as either date in the "between"
    operation.  Both can be used together, as well.  See mantimespan.html for
    details.

  * Changed several functions to take const data types so that data can't be
    changed accidentally.

  * Fixed a bug in get_day_num() where the wrong month lengths were being used
    for making sure the user-specified day is valid for the month. (Andrew
	 Turnquist)

version 2.0 - October 9, 2004 :
===============================
  * Changed argument system and parsing.

  * Output format is entirely different; consult the documentation for details.

  * Output of a date can now be either long (months are represented by their
   names) or short (months are represented by their numeric value).

  * Multiple outputs are now possible for one given operation--a date, number
    of days, number of hours, number of minutes, and number of seconds, or any
    combination of those can be simultaneously output; consult the
    documentation for details.

  * File I/O features have been removed in favor of the native scripting
    abilities of modern shells.

  * Deleted pathchooser.cpp, fileops.cpp, errorcheck.cpp, and display.cpp and
    dropped all functions contained in those files.

  * Added util.cpp and moved basename() and isleap() there, as well as
    creating print_date(), get_month_num(), get_day_num(), and get_year_num()
    to provide proper error checking in retrieving values from the command
    line.

  * Renamed the structs datestruct, flagstruct, and filestruct to Date, Flag,
    and File, respectively.

  * Renamed calccustomdays(), calccustomhours(), calccustomminutes(), and
    calccustomseconds() to calc_days_between(), calc_hours_between(),
    calc_minutes_between(), and calc_seconds_between(), respectively.

  * Dropped calcfuture().

  * Fixed some obscure bugs in calcdate and changed its return type.

  * Changed various return types and variable types to enforce the fact that
    date components cannot be negative.

  * Added simulated case-insensitive string comparison.
  
  * Dropped char * const smonths[], as it is no longer needed.

  * Changed all "char * const" constants to "const char * const", as these
    pointers are no longer assigned to other pointers.

  * Updated documentation to reflect the new argument system.

  * Fixed a mispelling in a ChangeLog entry for version 1.1.

  * Minor changes to ChangeLog format.

  * Created ChangeLog-pre2.0 and moved all ChangeLog entries for versions
    prior to 2.0 to that file.

  * Removed mantimespan.txt and mantimespan-win32.txt.

  * Updated project support files for Microsoft Visual C++ 6 and Visual
    Stuido.NET 2003.
