a "call" parameter, which is a reference to a function to call for the
hook.
-An optional "scan" parameter, if set to a true value, makes the hook be

-be run twice per page build, so avoid doing it for expensive hooks.

An optional "last" parameter, if set to a true value, makes the hook run
after all other hooks of its type. Useful if the hook depends on some other
hook being run first.

Use this to hook into ikiwiki's cgi script. Each registered cgi hook is
called in turn, and passed a CGI object. The hook should examine the

terminate the program.
