# @Description: 
#    This file defines the flex_extract's available installation
#    parameters and puts them together for the call of the actual 
#    python installation script. It also does some checks to 
#    guarantee necessary parameters were set.
#
# @History:
#    Leopold Haimberger; Aug 2020
#       added new parameter for a system installation 
#       (seperate executable and user directories)
#    Anne Tipka; July 2022
#       Adapted to use on Bologna servers
