README for yapo 0.2.x

To get working function keys F1-F4 with xterm append the 
following lines to /etc/X11/app-defaults/Xterm or use aterm, 
which works without these modifications:

*VT100.translations: #override \
   ~s<Key>F1:  string(0x1b) string("[11~") \n\
   ~s<Key>F2:  string(0x1b) string("[12~") \n\
   ~s<Key>F3:  string(0x1b) string("[13~") \n\
   ~s<Key>F4:  string(0x1b) string("[14~") \n\
	    
Note: this is not a problem of yapo, but of the standard 
configuration of xterm.
