+
+This hook can be used to implement arbitrary access methods to control
+when a page being edited can be saved using the web interface (commits
+from revision control bypass it).
+
+When a page is about to be saved, each registered cansave hook is
+called in turn, and passed the page name, the edited content, a CGI
+object and a session object.
+
+The return value of a cansave hook is interpreted the same as for the
+canedit hook.
