  laser facilities, providing general-purpose graphical user interface 
  applications to fulfill various tasks, such as image DAQ, 
  data post-processing, data correlation analysis and FEL physics 
  calculations, etc. Friendly user interative approaches are subtly 
  designed, as well as the straight-forward distribution manner. 
  
  ``felapps`` is the beginning phase to the world of python-powered software
  ecosystem that could be served as the infrastructure for the future 
  versatile large-scale scientific facilities.
  
  .. warning:: Before installing ``felapps``, another python package 
      ``beamline`` is required, so install that package first, 
      see `the documentation <https://archman.github.io/beamline>`_.
  
  Brief guide to the users:
  
  1. type ``runfelapps`` or ``appdrawer`` in the terminal to open the main 
     app portal of ``felapps``;
  2. in [i]python terminal, first ``import felapps``, then call 
     ``felapps.imageviewer.run()`` to open ``imageviewer`` app, the same rule
     applies to other apps:
      * ``dataworkshop``
      * ``cornalyzer``
      * ``felformula``
      * ``wxmpv``
