================================================    Updated:
		Environment variables affecting LibGII behaviour    990515
		================================================    


GII_INPUT	- Input source(s) and/or filter(s) to use when giiOpen() is
		  called with a NULL argument.

		  Format: <input>[:<inputargs>]
		  
		  Multiple inputs can be specified using the notation:
		  (<i1>):(<i2>):(<i3>) etc...

GGI_DEBUG	- Debug level for LibGII:
                    0 or unset - debug output is offdebugging is off
		    255        - all debug output is on
		  You may also 'or' any of the following together:
		      2  - debug core
		     32  - misc debugging output
		     64	 - debug dynamic library handling
		    128  - debug event handling

GGI_DEBUGSYNC	- Turn on synchronous debug output. Flush the output buffers
		  before returning from GIIDPRINT calls.
		  Note that the last two environment variable really begin
		  with GGI, and not GII.

GII_CTRLALT_VTSWITCH is specific to the linux-kbd inputlib. See the file
inputs.txt for description of that.
