/* External API usage documentation. Please update when you change how this method works. */
/*! @page statusesupdate statuses/update
@section Description
Updates the authenticating user's status. Requires the status parameter specified below.
Request must be a POST.
@par URL pattern
/api/statuses/update.:format
@par Formats (:format)
xml, json
@par HTTP Method(s)
POST
@par Requires Authentication
Yes
@param status (Required) The URL-encoded text of the status update.
@param source (Optional) The source application name, if using HTTP authentication or an anonymous OAuth consumer.
@param in_reply_to_status_id (Optional) The ID of an existing status that the update is in reply to.
@param lat (Optional) The latitude the status refers to.
@param long (Optional) The longitude the status refers to.
@param media (Optional) a media upload, such as an image or movie file.
@sa @ref authentication
@sa @ref apiroot
@subsection usagenotes Usage notes
@li The URL pattern is relative to the @ref apiroot.
@li If the @e source parameter is not supplied the source of the status will default to 'api'. When authenticated via a registered OAuth application, the application's registered name and URL will always override the source parameter.
@li The XML response uses <a href="http://georss.org/Main_Page">GeoRSS</a>
to encode the latitude and longitude (see example response below <georss:point>).
@li Data uploaded via the @e media parameter should be multipart/form-data encoded.
@subsection exampleusage Example usage
@verbatim
curl -u username:password http://example.com/api/statuses/update.xml -d status='Howdy!' -d lat='30.468' -d long='-94.743'
