        This is the free xaero release.

        The current version can be obtained via anonymous ftp from
	ftp.informatik.uni-stuttgart.de (currently 129.69.211.2) in the
	directory /pub/AERO.

	To compile this release you need:

	     X11R5 (not tested with an earlier version)
             Athena Widget set
             FWF (Free Widget Foundation widget set Version 3.62 or newer) 
             XPM (X PixMap Version 3.2g or newer)
	     Ansi C Compiler (best: gcc Version 2.3.3 or newer)
	   
	There are a few Makefiles adapted to different operating systems.
	First check the Makefile. To use the makefile adapted to your OS type
	'make -f <name of Makefile (i.e. Makefile.linux)>'. Some path
	variables will be listed by typing 'make help'. These variables
	should be adapted to your local system. To compile xaero type 
	'make all'. If you want to install xaero (in a global path) type
	'make install'. See Makefile for further information.


	If you only want to install the binaries, put the 'xaero' file in a
	directory which is listed in your 'path'-variable. Place the
	application default file in directory '/usr/lib/X11/app-defaults'
	(see X manual for detail). If you don't have write permission to
	these directory, you have to add the app-defaults path to the
	XAPPLRESDIR env by typing: 'setenv XAPPLRESDIR <directory where the
	app-def file can be found>'.
	
	Now 'rehash' and start xaero.

	Here is a FAQ:
	        
Q:        I've recently downloaded the xaero package and seem to be having
Q:	some difficulty getting it to run. I keep on getting the following
Q:	message:
Q:		Error: Widget EM_Darstellung3D has zero width and/or height

A:	There are some machines which don't support local application-
A:	defaults. In this case you have to place the app-defaults/XAero
A:	into a system app-defaults directory (for example:/usr/lib/X11/app-defaults,
A:	/usr/local/X11R5/lib/app-defaults). If you don't have write
A:	permission to this directory, you can add the application-file to
A:	your X server resource database via
A:
A:		'xrdb -merge app-defaults/XAero' 
A:
A:	If your system supports the XAPPLRESDIR environment, it probably
A:	does not accept a list of app-defaults Directories. In this case 
A:
A:		'setenv XAPPLRESDIR $HOME/app-defaults'
A:
A:	may work.
