by the external editor helper application (NB: that fatal error was probably
a PHP 4/5 thing, I'm using PHP 5 here).
2) adding some extra information for the helper, this should all be made
a little more logical (only pass on as much information as needed to
construct the proper URLs)
allows editing wiki pages or files with an external application, by using
an intermediate helper application (such as the reference one in
extensions/ee) which fetches the data and transmits the changes back to the
server.
This version adds external editor support for uploaded files, as well as for
pages. More operations, such as diffs and merges, should support
application/external-editor in the future.
See extensions/ee/README for some more info on the concept. Documentation
will also be placed on http://meta.wikimedia.org/wiki/Help:External_editors
