@@@ -321,41 -321,26 +321,61 @@@ This hook should avoid directly redirec
  since it's sometimes used to test to see which pages in a set of pages a
  user can edit.
  
 +### 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`.
 +
+ ### checkcontent
+ 	
+ 	hook(type => "checkcontent", id => "foo", call => \&checkcontent);
+ 
+ This hook is called to check the content a user has entered on a page,
+ before it is saved, and decide if it should be allowed.
+ 
+ It is passed named parameters: `content`, `page`, `cgi`, and `session`. If
+ the content the user has entered is a comment, it may also be passed some
+ additional parameters: `author`, `url`, and `subject`. The `subject`
+ parameter may also be filled with the user's comment about the change.
+ 
+ Note: When the user edits an existing wiki page, the passed `content` will
+ include only the lines that they added to the page, or modified.
+ 
+ The hook should return `undef` on success. If the content is disallowed, it
+ should return a message stating what the problem is, or a function
+ that can be run to perform whatever action is necessary to allow the user
+ to post the content.
+ 
  ### editcontent
  
  	hook(type => "editcontent", id => "foo", call => \&editcontent);
