COMPILE
=======
  
  To be able to compile on Linux, you must have the latest SDL
  package from http://libsdl.org. The recent stable release as of time of
  this writing is 1.2.0. You will need the development libraries for Linux.
  
  The provided makefile is written for the GNU C++ compiler but can also
  be easily adjusted for other compilers.
  
  It is very likely that if SDL is supported on your system, than Yape can
  be compiled and run. Hence, a BeOS port is also possible, and Yape has
  been succesfully compiled on Windows, and 64 bit Solaris systems as well.
  
  Once the libraries and header files are installed, you should
  extract the source tarball to a directory, and simply type:
  
  make
  
  If the compilation finished with no error, you can type:
  
  ./yapelin [PRG/TAP filename]
  
  to start the emulator, where filename is optional.
  
USAGE
=====

  The user interface isn't yet ready, so you MUST memorise a couple
  of keyboard shortcuts:
  
  F12 or ESCAPE : exits the emulator
  F11		: soft reset
  LCTRL + F11	: forced reset (memory remains intact)
  SHIFT + F11	: hard reset (clear memory, reloads ROMs, rewinds tape)
  
  F5		: press PLAY on tape
  F6		: press STOP on tape
  
  F9		: quick debugger
  F10		: save current settings

  LALT + G	: display frame rate on/off  
  LALT + J	: toggle joystick emulation (via crsr keys)
  LALT + I	: switch emulated jostick port
  LALT + S	: force frame rate to 50 MHz (original speed)
  
  Internal disk LOAD/SAVE operations are supported to the current
  file system directory. This means that an exact filename match will load
  the requested program, similarly can you save a file.
  
  Full ROM banking is supported, currently only via the yape.ini configuration
  file. You must fill in the path for the relevant ROM image you intend to use.
  However, Yape supports some internal ROMs already. These are:
  
  - 'BASIC' 	 - the ROM image containing the BASIC interpreter
  - 'KERNAL' 	 - the system kernal ROM image
  - '3PLUS1LOW'  - the low bank ROM image of the built-in plus/4 software
  - '3PLUS1HIGH' - the high bank ROM image of the built-in plus/4 software
  
KEYBOARD MAPPINGS
=================

  Unfortunately all X11 servers map the keys at different positions, so your
  mileage may vary. I have yet no info on how to solve this issue.
  
  There are several keys that need to be mapped to the emulator keyboard
  differently. These are:
