-
-	Just in case you _may_ want to use this in your own proggie (urgh)
-	let's put some documentation here :)
-
-** FUNCTIONS **
-
-void oxl_setpalette(rgb *pal)
-
-	pal is a table containing three ints (r,g,b) for every color.
-	the values vary 0..255. 
-
-void oxl_doframe(char *vscr)
-
-	blits the contents of the offscreen buffer to the screen.
-	the size of the buffer is BUFW * BUFH * 8 bits.
-
-int oxl_timer(void)
-
-	the current timer value. the number of timer ticks per second is
-	defined by the DEMOHZ constant.
-
-void oxl_doaudio(int*(player()));
-
-	fills the audio output buffers up to 50%.
-	
-	player is a user-specified function returning a pointer to some raw
-   audio data (e.g. the mixer output for the next row of a pattern)
-
-	the first int of the data is the length of the rest (in ints).
-
-	the buffer is int* but the data is 16bit unsigned. values going out
-   of the range 0..65535 will be clipped.
-
-	AUFREQ specifies the output frequency.
-
-void oxl_init_video(void);
-
-   adjusts the display for the demo. 	
-	oxl_doframe and oxl_setpalette need this.	
-
-void oxl_init_audio(int rowtix);
- 	
-	inits the audio stuff, possibly changing the value of AUFREQ. 
-   rowtix is the maximum length (in ticks) of an audio chunk produced
-   by int*(player()). (the 'physical length' in samples is therefore
-   rowtix*AUFREQ/DEMOHZ)
-
-   oxl_doaudio needs this.  does nothing if nosound.
-
-void oxl_init_timer(void);
-
-	starts the timer. oxl_timer needs this.
-	
-	with sounds on, the timing is actually based on the byte counter of
-   the sound device but put this in your code anyway.
-
-void oxl_end(void);
-
-	closes the multimedia subsystems. these things should be done
-   automatically when the program terminates, so you really don't need
-   this function.
-
-** CONSTANTS REQUIRED **
-
-	AUDIO (0/1)
-	VIDEO (vga/X11)
-	BUFW, BUFH (buffer size)
-	DEMOHZ (timer ticks per second)
-
-** THINGS TO DO **
-
-	- A guard process that tries to keep up the audio even if the main
-     loop is frozen. (e.g. if the svgalib screen is not active or if
-     you move the window in X)
-
-	- Make sure the window start address is properly aligned for the
-     maximum performance.
-
-	- Do not calculate the contents of the buffer if the screen/window
-     is not visible.
-
-	- A variable palette size: if the palette fits in the end of the
-     default colormap, we have to be able to use it instead of rudely
-     using a private map.
-   
-   - Support for visual depths other than 8bpp.
-
-	- Support for 16-bit multimedia sound systems. Stereo?
-
-	- mSDoS support (for dummies)
-
-	- AAlib support
-
-	- An automatical reselection of X11 gfx mode to best fit the size of
-     the buffer.
-     
-   - X fullscreen mode
-   
-   - X rootwindow mode
-
-	- Etc etc... but still trying to keep it in a relevant size ;)
