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.
