 Intl
 ====
 
 This package provides internationalization and localization facilities,
 including message translation, plurals and genders, date/number formatting
 and parsing, and bidirectional text.
 
 ## General
 The most important library is [intl][intl_lib]. It defines the [Intl][Intl]
 class, with the default locale and methods for accessing most of the

       print(remainingEmailsMessage(1, "Fred"));
 
 However, since the typical usage for a plural or gender is for it to
 be at the top-level, we can also omit the [Intl.message][Intl.message] call and
 provide its parameters to the [Intl.plural][Intl.plural] call instead.
 
       remainingEmailsMessage(int howMany, String userName) => 
         Intl.plural(
           howMany,
           zero: 'There are no emails left for $userName.',
           one: 'There is one email left for $userName.',
           other: 'There are $howMany emails left for $userName.'),
           name: "remainingEmailsMessage",
           args: [howMany, userName],
           desc: "How many emails remain after archiving.",
-          examples: {'number': 42, 'userName': 'Fred'});
+          examples: {'howMany': 42, 'userName': 'Fred'});
 
 Similarly, there is an [Intl.gender][Intl.gender] message, and plurals
 and genders can be nested.
 
       notOnlineMessage(String userName, String userGender) => 
         Intl.gender(
           userGender,
           male: '$userName is unavailable because he is not online.',
           female: '$userName is unavailable because she is not online.',
           other: '$userName is unavailable because they are not online'),
