The manual notes interface allows you to add notes to the online
version of the PHP-GTK manual. These notes are then shared with other
PHP users when they browse the manual online.
Periodically, the developers may go through the notes and incorporate
the information in them into the documentation proper.
These notes are only visible at gtk.php.net
because that's where the database that stores them is located. If (when) the
PHP-GTK website is mirrored in several locations, we'll work out a way of
having the notes available across all the mirror sites.
