s:547:"Several methods are available:
* Upload file contents directly, using the <var>$1file</var> parameter.
* Upload the file in pieces, using the <var>$1filesize</var>, <var>$1chunk</var>, and <var>$1offset</var> parameters.
* Have the MediaWiki server fetch a file from a URL, using the <var>$1url</var> parameter.
* Complete an earlier upload that failed due to warnings, using the <var>$1filekey</var> parameter.
Note that the HTTP POST must be done as a file upload (i.e. using <code>multipart/form-data</code>) when sending the <var>$1file</var>.";
