+ // State_LOGIN_AUTH_INIT
+// Given a vector of login uris (usually just one), perform a dns lookup for the 
+// SRV record from each URI. I think this is used to distribute login requests to 
+// a single URI to multiple hosts.
+// This is currently a synchronous action. (See LLSRV::rewriteURI() implementation)
+// On dns lookup error the output uris == the input uris.
+//
+// Input: A vector of login uris
+// Output: A vector of login uris
+//
+// Code:
+// std::vector<std::string> uris;
+// LLViewerLogin::getInstance()->getLoginURIs(uris);
+// std::vector<std::string>::const_iterator iter, end;
+// for (iter = uris.begin(), end = uris.end(); iter != end; ++iter)

+//	rewritten = LLSRV::rewriteURI(*iter);
+//	sAuthUris.insert(sAuthUris.end(),
+//					 rewritten.begin(), rewritten.end());
+// }
+// sAuthUriNum = 0;
+
+// Authenticate 
+// STATE_LOGIN_AUTHENTICATE
+// Connect to the login server, presumably login.cgi, requesting the login 
+// and a slew of related initial connection information.
+// This is an asynch action. The final response, whether success or error
+// is handled by STATE_LOGIN_PROCESS_REPONSE.
+// There is no immediate error or output from this call.
+// 
+// Input: 
+//  URI
+//  Credentials (first, last, password)
+//  Start location
+//  Bool Flags:
+//    skip optional update
+//    accept terms of service
+//    accept critical message
+//  Last exec event. (crash state of previous session)
+//  requested optional data (inventory skel, initial outfit, etc.)

+//	gAcceptCriticalMessage,
+//	gLastExecEvent,
+//	requested_options,
+//	hashed_mac_string,
+//	LLAppViewer::instance()->getSerialNumber());
+
+//
+// Download the Response
+// STATE_LOGIN_NO_REPONSE_YET and STATE_LOGIN_DOWNLOADING
+// I had assumed that this was default behavior of the message system. However...
+// During login, the message system is checked only by these two states in idle_startup().
+// I guess this avoids the overhead of checking network messages for those login states
+// that don't need to do so, but geez!
+// There are two states to do this one function just to update the login
+// status text from 'Logging In...' to 'Downloading...'
+// 
+
+//
+// Handle Login Response
+// STATE_LOGIN_PROCESS_RESPONSE
+// 
+// This state handle the result of the request to login. There is a metric ton of
+// code in this case. This state will transition to:
+// STATE_WORLD_INIT, on success.
+// STATE_AUTHENTICATE, on failure.
+// STATE_UPDATE_CHECK, to handle user during login interaction like TOS display.
+//
+// Much of the code in this case belongs on the viewer side of the fence and not in login. 
+// Login should probably return with a couple of events, success and failure.
+// Failure conditions can be specified in the events data pacet to allow the viewer 
+// to re-engauge login as is appropriate. (Or should there be multiple failure messages?)
+// Success is returned with the data requested from the login. According to OGP specs 
+// there may be intermediate steps before reaching this result in future login 
+// implementations.
