# http://cxc.harvard.edu/chips/ahelp/chips4.html#Running_ChIPS_in_batch_mode
#ChIPS always requires the presence of a X server, even when used in a script or
#program which does not produce on-screen plots (e.g. the "window.display" preference
#has been set to "false"). When a ChIPS server is started, it tries to connect to the
#X-display indicated by the DISPLAY environment variable, which can result in one of three cases:
# DISPLAY environment variable is valid
# In this case the ChIPS server will use the indicated X display for its plots.
# DISPLAY environment variable is invalid or unset
# it will try to start up a temporary, virtual, framebuffer using the Xvfb program.
# If this works then the ChIPS commands will work, including calls to print_window(),
# but there will be no on-screen display.
# No DISPLAY and no Xvfb
# If the Xvfb program does not exist on your system then the server will fail to start
# up and report the following:
# chips ERROR: Failed to open DISPLAY or Xvfb session- exiting chipsServer
