		      The Screen NAVigator, ver 1.21 August 1990
			     Copyright (c) 1989 by Avner Ben

	  The  Screen	Navigator  is	an  object-oriented   device-independent
	  character-graphics  driver  package,	written  in  the  C++  language,
	  distributed as C++  source code.   For technical information	refer to
	  the documentation files.

	  CONDITIONS FOR USE.
	  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

	  The Screen NAVigator software package (henceforth "SNAV"), consists of
	  the  files  of   characters  whose  names   are  listed  in  the  file
	  "contents.prn". These files are originally distributed compressed into
	  an archive file, for example	named	"snav121.zip".   The   following
	  specifies the conditions for holding, distributing and using both  the
	  whole of the package, and each of these files alone.

	  The right to hold and distribute.
	  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

	  SNAV is "Shareware".  No matter if you have payed for SNAV or not, you
	  are free to  keep a copy  of SNAV, and  distribute other copies  among
	  your	friend	and  colleagues,  as  long  as	each copy is kept in the
	  complete original form, and neither the whole package nor any file  in
	  it is modified  in any way,  and as long  as money is  not charged for
	  that, that is, that you do not  sell SNAV.  You are free to  print the
	  source  and  documentation  files  for  your	private  use.  All these
	  activities are permitted even without registering your copy.

	  BBS operators and Software Interest Groups may charge handling fee for
	  distribution, but not more than $10.	 They are allowed to change  the
	  archiving method, but  provided all the  files are included,	complete
	  and unchanged.
	   The duty to register.
	  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
	  You must register one  or more copies of  SNAV, If you intend (or have
	  already started) to compile SNAV,  either in the distribution form  or
	  modified,  in  order	to  incorporate  the  object-code  in any useful
	  software.   By "useful  software" is  meant here  any software that is
	  implemented either in-house or  on a client's computer,  regardless of
	  the  fee  charged  for  that,  if  any.  This includes games, software
	  instruction, and  utility programs,  as well,  even if  these are held
	  in-house  and  free  of  charge.  You need not  register  SNAV (though
	  you still may), if your usage amounts to  exercises  and   experiment-
	  ation, having no permanent result, subject to the next paragraph.

	  You also must register SNAV if you continue compiling it or having any
	  other use  for it,  for more	than 30  days after  obtaining the first
	  copy, even if you do not intend  to use it commercially. That is,  you
	  are given 30 days to evaluate the product non-commercially.

	  You should register each copy that  may be in simultaneous  use.   For
	  example, If you employ three developers, and each may be using a  copy
	  of SNAV or  part of it,  either on the  same or on  different project,
	  then you must  register three copies.   However, if  you are the  only
	  developer, and you modify SNAV for use in various projects, you should
	  register one copy.

	  Once a  copy of  SNAV is  registered, you  are allowed  to modify  the
	  various  source  files  to  fit  your  specific  needs, terminology or
	  standards, provided that each  file retains the original  filename and
	  the  copyright  notice  in  its  beginning.	 If  you  wish to change
	  filenames  or  split	files,	then  each  spawned  file  must  bear my
	  copyright notice, followed by a  description of its origin, the  exact
	  modifications, and the individuals responsible for them.

	  Modified  copies  of	SNAV  may  not	be  distributed,  other than for
	  internal software-project management purposes, and provided each  copy
	  has been registered.

	  Holding  SNAV,  however  obtained,  for  more  than  30  days, implies
	  acceptance of the terms above.

	  Registering  should  be  done  using	the  form  printed from the file
	  "register.frm".

	  Registration applies only to using the code in  software  development.
	  The resulting compiled commercial  applications  are	not  subject  to
	  royalties, registration or copy-protection of any kind, by SNAV.
