+  client dll readme.txt
+-------------------------
+
+This file details the structure of the half-life client dll,  and
+how it communicates with the half-life game engine.
+
+
+Engine callback functions:
+
+Drawing functions:
+	HSPRITE SPR_Load( char *picname );
+		Loads a sprite into memory, and returns a handle to it.
+
+	int  SPR_Frames( HSPRITE sprite );
+		Returns the number of frames stored in the specified sprite.
+
+	int  SPR_Height( HSPRITE x, int frame )
+		Returns the height, in pixels, of a sprite at the specified frame.  
+		Returns 0 is the frame number or the sprite handle is invalid.
+
+	int  SPR_Width( HSPRITE x, int f )
+		Returns the width, in pixels, of a sprite at the specified frame.  
+		Returns 0 is the frame number or the sprite handle is invalid.
+
+	int  SPR_Set( HSPRITE sprite, int r, int g, int b );
+		Prepares a sprite about to be drawn.  RBG color values are applied to the sprite at this time.
+
+
+	void  SPR_Draw( int frame, int x, int y );
+		Precondition:  SPR_Set has already been called for a sprite.
+		Draws the currently active sprite to the screen,  at position (x,y), where (0,0) is
+		the top left-hand corner of the screen.
+
+
+	void  SPR_DrawHoles( int frame, int x, int y );
+		Precondition:  SPR_Set has already been called for a sprite.
+		Draws the currently active sprite to the screen.  Color index #255 is treated as transparent.
+
+	void  SPR_DrawAdditive( int frame, int x, int y );
+		Precondition:  SPR_Set has already been called for a sprite.
+		Draws the currently active sprite to the screen,  adding it's color values to the background.
+
+	void  SPR_EnableScissor( int x, int y, int width, int height );
+		Creates a clipping rectangle.  No pixels will be drawn outside the specified area.  Will
+		stay in effect until either the next frame,  or SPR_DisableScissor is called.
+
+	void  SPR_DisableScissor( void );
+		Disables the effect of an SPR_EnableScissor call.
+
+	int	 IsHighRes( void );
+		returns 1 if the res mode is 640x480 or higher;  0 otherwise.
+
+	int	 ScreenWidth( void );
+		returns the screen width, in pixels.
+
+	int	 ScreenHeight( void );
+		returns the screen height, in pixels.
+
+// Sound functions
+	void PlaySound( char *szSound, int volume )
+		plays the sound 'szSound' at the specified volume.  Loads the sound if it hasn't been cached.
+		If it can't find the sound,  it displays an error message and plays no sound.
+
+	void PlaySound( int iSound, int volume )
+		Precondition:  iSound has been precached.
+		Plays the sound, from the precache list.
+
+
+// Communication functions
+	void  SendClientCmd( char *szCmdString );
+		sends a command to the server,  just as if the client had typed the szCmdString at the console.
+
+	char *GetPlayerName( int entity_number );
+		returns a pointer to a string, that contains the name of the specified client.  
+		Returns NULL if the entity_number is not a client.
+		
+
+	DECLARE_MESSAGE(),  HOOK_MESSAGE()
+		These two macros bind the message sending between the entity DLL and the client DLL to
+		the CHud object.
+
+		HOOK_MESSAGE( message_name )
+			 This is used inside CHud::Init().  It calls into the engine to hook that message
+			 from the incoming message stream.
+			 Precondition:  There must be a function of name UserMsg_message_name declared
+			 for CHud.  Eg,  CHud::UserMsg_Health() must be declared if you want to 
+			 use HOOK_MESSAGE( Health );
+
+		DECLARE_MESSAGE( message_name )
+			For each HOOK_MESSAGE you must have an equivalent DECLARE_MESSAGE.  This creates
+			a function which passes the hooked messages into the CHud object.
+
+
+	HOOK_COMMAND(),  DECLARE_COMMAND()
+		These two functions declare and hook console commands into the client dll.
+		
+		HOOK_COMMAND( char *command, command_name )
+			Whenever the user types the 'command' at the console,  the function 'command_name'
+			will be called.
+			Precondition: There must be a function of the name UserCmd_command_name declared
+			for CHud. Eg,  CHud::UserMsg_ShowScores() must be declared if you want to
+			use HOOK_COMMAND( "+showscores", ShowScores );
+
+		DECLARE_COMMAND( command_name )
+			For each HOOK_COMMAND you must have an equivelant DECLARE_COMMAND.  This creates
+			a function which passes the hooked commands into the CHud object.
