 OPTIONS
 -------
 
---strict::
+--[no-]strict::
        Do not try <directory>/.git/ if <directory> is no Git directory.
 
 --timeout=<n>::
        Interrupt transfer after <n> seconds of inactivity.
 
+--stateless-rpc::
+       Perform only a single read-write cycle with stdin and stdout.
+       This fits with the HTTP POST request processing model where
+       a program may read the request, write a response, and must exit.
+
+--advertise-refs::
+       Only the initial ref advertisement is output, and the program exits
+       immediately. This fits with the HTTP GET request model, where
+       no request content is received but a response must be produced.
+
 <directory>::
        The repository to sync from.
