 + 
 +noresm2tape copies the output of a NorESM case from NorStore's disk area to NorStore's tape resource. The output folder should be organised in the standard CCSM way (e.g., atmospheric output is expected in 'atm/hist'). If that is not the case, please use the command disk2tape instead. 
 + 
 +**IMPORTANT:** It is highly recommended to run the script in background using the nohup command, e.g.,  
 + "''nohup /projects/NS2345K/tools/noresm2tape <path on disk> <path on tape> &''". Make sure not to forget the "&" at the end of the line. After submitting the script with nohup, it is safe to log out. You will receive a notification email when the transfer to tape is completed.

 +  
 +Purpose: Lists the names of files that are archived in a given directory on tape.  
 +
 +Description: The script relies on the existence of a checksum file, with extension 
 +             md5.tar, that is stored in the archive directory. 
 +
 +             If exactly one checksum file exists then directory path is sufficient 
 +             as input argument. However, if two or more checksum file exist then 
 +             the absolute path to the checksum file has to be provided.
