/*
 * ClientApi - the Perforce client API
 *
 * Basic flow:
 *
 *	ClientUser ui;
 *	ClientApi client;
 *
 *	// SetPort(), SetProtocol() must happen _before_ the Init().
 *
 *	client.SetPort( somefunctionof( client.GetPort() ) ); //optional
 *	client.SetProtocol( "var", "value" ); //optional
 *
 *	client.Init( e );
 *
 *	// GetClient(), SetBreak(), SetProg() must happen _after_ the Init().
 *
 *	client.SetBreak( &k );      // optional
 *
 *	client.SetProg( "MyApp" );  // optional
 *
 *	client.SetVersion( "version" ); // optional
 *
 *	client.SetClient( somefunctionof( client.GetClient() ) ); //optional
 *	client.SetCwd( somefunctionof( client.GetCwd() ) ); //optional
 *	client.SetUser( somefunctionof( client.GetUser() ) ); //optional
 *
 *	while( !client.Dropped() )
 *	{
 *	    client.SetArgv( argc, argv )
 *	    client.Run( func, &ui )
 *	}
 *
 *	return client.Final( e );
 *
 * Public methods:
 *
 *	ClientApi::SetUi() - reset the ClientUser object used
 *	ClientApi::SetProtocol() - ask for special server treatment
 *	ClientApi::GetProtocol() - get a protocol capability
 *		SetProtocol() is called before Init(); GetProtocol() after Run().
 *
 *	ClientApi::Init() - establish connection and prepare to run commands.
 *
 *	ClientApi::SetVar() - set variable
 *	ClientApi::SetVarV() - set variable using var=value syntax
 *	ClientApi::SetArgv() - set unnamed variables (args for Run())
 *	ClientApi::GetVar() - get variable
 *
 *	ClientApi::Run() - run a single command
 *	ClientApi::Final() - clean up end of connection, returning error count.
 *	ClientApi::Dropped() - check if connection is no longer serviceable
 *	ClientApi::GetErrors() - get count of errors returned by server.
 *
 *	ClientApi::RunTag() - run a single command (potentially) asynchronously.
 *	ClientApi::WaitTag() - wait for a RunTag()/all RunTag()s to complete.
 *
 *	ClientApi::SetCharset()
 *	ClientApi::SetClient()
 *	ClientApi::SetCwd()
 *	ClientApi::SetHost()
 *	ClientApi::SetLanguage()
 *	ClientApi::SetPassword()
 *	ClientApi::SetPort()
 *	ClientApi::SetUser() - set client, current directory, host, port, or
 *		user, overridding all defaults.  SetPort() must be called
 *		before Init() in order to take effect.  The others must be
 *		set before Run() to take effect.
 *
 *		SetCwd() additionally searches for a new P4CONFIG file.
 *
 *	ClientApi::SetBreak() - set a subclassed KeepAlive object (only
 *		method IsAlive returns zero on dropped connection). Must
 *		be called after Init() it order to take affect.
 *
 *	ClientApi::SetProg() - set the name of the application program,
 *		this will show up in 'p4 monitor' and server log output.
 *		Should be called before Init().
 *
 *	ClientApi::SetVersion() - sets the version string of the application.
 *		If not called, the version defaults to protocolClient. This
 *		will be appended to the program name in 'p4 monitor' and
 *		server log output.  It should be called after Init() and
 *		before each call to Run().
 *
 *	ClientApi::SetTicketFile() - set the location of the users ticketfile,
 *		must be the full pathname to the file and not a directory.
 *
 *	ClientApi::SetTrustFile() - set the location of the trustfile,
 *		must be the full pathname to the file and not a directory.
 *
 *	ClientApi::SetExecutable() - set the location of the physical client
 *		executable program file. This is needed by the network
 *	        parallelism features (parallel sync/submit etc.) so that they
 *	        can spawn more copies of the program as needed.
 *
 *	ClientApi::DefineCharset()
 *	ClientApi::DefineClient()
 *	ClientApi::DefineHost()
 *	ClientApi::DefineLanguage()
 *	ClientApi::DefinePassword()
 *	ClientApi::DefinePort()
 *	ClientApi::DefineUser() - sets client, port, or user in the registry
 *		and (so as to take permanent effect) then calls SetClient(),
 *		etc. to take immediate effect.
 *
 *	ClientApi::GetBuild()
 *	ClientApi::GetCharset()
 *	ClientApi::GetClient()
 *	ClientApi::GetCwd()
 *	ClientApi::GetExecutable()
 *	ClientApi::GetHost()
 *	ClientApi::GetLanguage()
 *	ClientApi::GetOs()
 *	ClientApi::GetPassword()
 *	ClientApi::GetPort()
 *	ClientApi::GetUser() - get current directory, client, OS, port or user,
 *		as determined by defaults or by corresponding set value.
 *		GetClient()/GetHost() are not valid until after Init()
 *		establishes the connection, because the hostname of the
 *		local endpoint may serve as the default client name.
 *
 *	Client::GetConfig() - get the filename pointed to by P4CONFIG, as
 *		determined by enviro::Config().
 *
 *	ClientApi::SetIgnorePassword() - This function ignores passwords
 *		that are found in the registry (NT), host environments or
 *		configuration files.  If this function is set then only
 *		passwords supplied through SetPassword() will be honored.
 *		Tickets continue to work as normal. Must be called before
 *		Init() in order to take affect.
