<usage>
-<p>HTTP Methods that are not conforming to the relevant RFCs are normally
-rejected by request processing in Apache HTTPD. To avoid this, modules
-can register non-standard HTTP methods they support.
-The <directive>RegisterHttpMethod</directive> allows to register such
-methods manually. This can be useful if such methods are forwarded
-for external processing, e.g. to a CGI script.</p>
+<p>This directive may be used to register additional HTTP methods. This is
+necessary if non-standard methods need to be used with directives that accept
+method names as parameters, or to allow particular non-standard methods to be
+used via proxy or CGI script when the server has been configured to only pass
+recognized methods to modules.</p>
