+This is used to edit a file.  It downloads the file, edits it
+locally using your editor, then uploads the result.
+
+The editor is C<$EDITOR>.  However if you use the alternate
+commands C<vi> or C<emacs> you will get those corresponding
+editors.
+
+NOTE: This will not work reliably for large files
