description = """
lumi-CrayPath adds the current CRAY_LD_LIBRARY_PATH to the front of LD_LIBRARY_PATH.

The module is not very sophisticated at this moment and will fail to properly
remove directories again when unloaded if directories appear in both
CRAY_LD_LIBRARYPATH and the unmodified LD_LIBRARY_PATH, but this does not seem
to happen in all current releases of the HPE Cray PE.

This module sets the environment variable _CRAYPATH_STORED_CRAY_LD_LIBRARY_PATH.
Tampering with that variable will cause silent failures of the module unload. It 
will fail to properly reset LD_LIBRARY_PATH.
