##   semi-automated script installing FairSoft, FairRoot and CbmRoot
#
# 24.05.2018 - switch to oct17p1 as dev version
# 31.01.2017 - make ROOT6 the default
# 17.12.2015 - split fairsoft directory into src and install
# 01.12.2015 - add selection of root version
# 17.07.2015 - introduce option to compile dev settings 
# 02.06.2015 - introduce parameters for individual package selection
# 13.03.2015 - initial version
