GUI URLs is a mechanism allowing projects to pass URLs to the client, for display as links in the GUI.

Projects can includes a file 'gui_urls.xml' in the project root directory, with the following form: ",html_text(" Your account View your account information and credit totals http://foo.project.com/blah.php?userid= Help Get help about SETI@home http://foo.project.com/help.php ... "),"

Each entry describes a GUI URL. The elements are: "; list_start(); list_item("name", "A short name, used e.g. as a menu item"); list_item("description", "An explanation, used e.g. as a rollover popup"); list_item("url", "The URL"); list_end(); echo " All items are macro-substituted as follows: "; list_start(); list_item(htmlspecialchars(""), "The user ID"); list_item(htmlspecialchars(""), "The team ID"); list_item(htmlspecialchars(""), "The host ID"); list_item(htmlspecialchars(""), "The user's account ID"); list_end(); page_tail(); ?>
