 # == Introduction
-# 
+#
 # This library extends the Time class:
 # * conversion between date string and time object.
 #   * date-time defined by RFC 2822
 #   * HTTP-date defined by RFC 2616
 #   * dateTime defined by XML Schema Part 2: Datatypes (ISO 8601)
 #   * various formats handled by Date._parse (string to time only)

 # == Design Issues
-#

 # === Specialized interface
-# 
+#
 # This library provides methods dedicated to special purposes:
 # * RFC 2822, RFC 2616 and XML Schema.
 # * They makes usual life easier.
-# 
+#
 # === Doesn't depend on strftime
-# 
+#
 # This library doesn't use +strftime+.  Especially #rfc2822 doesn't depend
 # on +strftime+ because:
-# 
+#
 # * %a and %b are locale sensitive
-# 
+#
 #   Since they are locale sensitive, they may be replaced to
 #   invalid weekday/month name in some locales.
 #   Since ruby-1.6 doesn't invoke setlocale by default,
 #   the problem doesn't arise until some external library invokes setlocale.
 #   Ruby/GTK is the example of such library.
