    NAME
      AF - a network-transparent audio server and client library for networked
      audio	devices.

    SYNOPSIS

      The AF audio server is a network transparent	system developed at Digital
      CRL for using	LoFi audio hardware in a distributed environment.

    CONNECTION NAME

      From the user's prospective, every AF	server has an audio connection of the
      form:

    			      hostname:portOffset

      This information is used by the application to determine how it should con-
      nect to the server.

      hostname
    	  The hostname specifies the name of the machine to which the audio
    	  device is physically connected.

      portOffset
    	  The portOffset is used to identify the audio server's	port on	host-
    	  name.	 For example, to run multiple audio servers on a given host
    	  simultaneously, you need to select a unique portOffset for each
    	  invocation of	an audio server.

      If the connection name to an audio server is not specified, then the
      environment variables	AUDIOFILE or DISPLAY will be used.

    ACCESS CONTROL
      The sample server provides two types of access control:  an authorization
      protocol which provides a list of ``magic cookies'' clients can send to
      request access, and a	list of	hosts from which connections are always
      accepted.

    BUGS
      If you encounter a repeatable	bug, please submit a problem report to () and
      include the source code if possible.

    COPYRIGHT

      Software in this distribution	of the AF Audio	Server is covered by copy-
      rights.  See the COPYRIGHTS file in the root directory of the	source kit.

      What you do with applications	you develop is your buisness; if you wish to
      contribute code to this distribution see below.

      In order to contribute software to the AF distribution, we suggest follow-
      ing the model	of the X Window	System.	 The following is the guide lines
      from that distribution.  Other terms will make it unlikely that we will
      include a contribution on subsequent releases; we do not wish	to spend our
      time with lawyers on a case by case basis.

      The MIT distribution of the X	Window System is publicly available, but is
      NOT in the public domain.  The difference is that copyrights granting
      rights for unrestricted use and redistribution have been placed on all of
      the software to identify its authors.	 You are allowed and encouraged	to
      take this software and build commerical products.

      Individuals or organizations wishing to contribute software to the public
      releases should use a	copyright notice that is no more restrictive than the
      sample given below.  In particular,

      o	  Do not place any restictions on what can be done with	this software
    	  (this	includes using the GNU "copyleft").

      o	  Do not include the words "All	rights reserved" unless	you have had
    	  a lawyer verify that you have	also explicitly	given away all of the
    	  necessary rights shown in the	samples.

      o	  Spell	out the	word "Copyright"; the phrase "(c)" is NOT a legal
    	  alternative to the c-in-circle symbol.

      o	  Put at least a one-line copyright at the top of EVERY	source file,
    	  if not the full copyright.  Also, the	copyright line or full notice
    	  MUST physically appear in each file.	Using the preprocessor to
    	  #include the copyright from some other file has no legal meaning
    	  (it can be used to incorporate common	strings	into the binary, but
    	  has no effect	on the status of the source code).

      o	  Things that are copyrighted are, by definition, not in the public
    	  domain.

      o	  A copyright notice similar to	the following is strongly recommended
    	  (replacing MIT with your organization's name and putting your	name
    	  and address at the bottom).
