+#   At TGCC they use 'one login' for multi-project allocation .

+#   You could get your different project info by 'ccc_myproject'
+#
+#   I recommand you first, supposing that the "Genci Allocation" you want to use
+#   as for projet group "genXXXX"
+#
+#   1) to add  in your "~/.bash_profile"
+#
+module switch dfldatadir dfldatadir/genXXXX

+#  If all is OK , you could install the code in interactive as usally
