  GAIN for the CS Division
  ------------------------
  Gain Momentum Version 3.0-43 is available for HP and Sparc systems in the 
  CS Division (Soda Hall); it is installed in /disks/barad-dur/gain on the
  Barad-dur.cs file server.  The Gain license server also runs on Barad-dur.
  (May 1996).

  Acquisition and licensing for Gain has been coordinated by Profs Wilensky 
  and Harrison.  There are about a dozen "floating" licenses for HP 9000/700
  and Sparc systems.  The vendor has provided these for use by CS research
  and instructional users.    Techninal support for Gain and other Sybase
  products is coordinated through these staff members:

	Kevin Mullally (kevinm@eecs)	for EECS TCS & Instructional systems
	Michael Short (mshort@cs)	for CS Division SWW systems
 

  Access for EECS Instruction
  ---------------------------
  Gain is accessed as /usr/local/gain on the EECS Instructional 
  systems in Soda Hall.  To start gain, type:

	set path = ( $path /usr/local/gain/gm30_43/bin ); rehash
	setenv GAINHOME /usr/local/gain/gm30_43
	gain -nolock +i

  If you are running Gain on a remote system over the network, 
  you will need to use the "setenv DISPLAY" and "xhost" commands 
  to redirect the Gain windows to your screen.  Please see 
  /share/b/pub/XWindows.help for more information.
   

  Product Description
  -------------------
  Gain Momentum is a multimedia development system that operates in a 
  multi-user, networked environment.   A limited number of licenses for 
  Gain Momentum and Gain RunTime have been granted for use in the CS 
  Division by Sybase, Inc.
  
  You can develop Gain Momentum applications by using the graphical user 
  interface, (GUI), by writing Gain Extension Language (GEL), or by using 
  a combination of both.  The GUI consists of menus, editors, dialog boxes 
  and palattes.  The GEL is a powerful scripting language.


  Getting Started
  ---------------
  When you start Gain Momentum for the first time, a "Welcome" message
  should appear, and you will be asked if you would like to create a
  home library.   Click on "Create Home Library".  The default is to
  create it in your home directory, but you may create it elsewhere
  (such as /home/tmp) if you have write permission there.  
  
  When you start Gain after that, you'll see a window, or "folder",
  that displays your personal library.  It will be empty at first.

  If you do not create a home library, you can still use the System 
  Library, but you do not have write permission to the System Library.

  Please see the manuals "Getting Started" and "User's Guide" for more 
  information.  

  Manuals
  -------
  A complete set of Gain manuals has been placed in 347 Soda for use
  within that lab.  Also, there are help buttons on the windows which 
  present detailed on-line information.

  The on-line "man" pages are stored in /usr/local/gain/gm30_43/man.
  You can add this to your own MANPATH environment variable with the
  command

	setenv MANPATH ${MANPATH}:/usr/local/gain/gm30_43/man

  Then type, for example, "man gain".
