The directory $NEMO/adm is the working directory from where incremental updates are processed. A nightly script can be set up by the NEMO system manager to export new files to all other relevant sites which run NEMO on a regular basis. All new files are bundled together in a tar file, to preserve directory structure and time stamps. These tar files are then sent to the central site or other sites. Similarly, other sites may export their tar files with updated files to your local site. These imported tarfiles are normally located in $NEMO/adm/import. Scripts import.csh and export.csh handle the traffic between tar files and the local directory. See also import(8NEMO) and export(8NEMO). Note that inter-site collisions are not always handled properly.
