+### cansave
+
+       hook(type => "cansave", id => "foo", call => \&cansave);
+
+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.
+
+### canremove
+
+       hook(type => "canremove", id => "foo", call => \&canremove);
+
+This hook can be used to implement arbitrary access methods to control when
+a page can be removed using the web interface (commits from revision control
+bypass it). It works exactly like the `canedit` hook.
+
+### canrename
+
+       hook(type => "canrename", id => "foo", call => \&canrename);
+
+This hook can be used to implement arbitrary access methods to control when
+a page can be renamed using the web interface (commits from revision control
+bypass it). It works exactly like the `canedit` and `canremove` hook,
+but is passed:
+* a CGI object
+* a session object
+* the named parameters `src`, `srcfile`, `dest` and `destfile`.
