The base release file for the current major version is used as the timestamp for cumulative updates. Make temporary copies of the master and archive on which to operate. These will have been archived when the base release for version ll was produced. This operation is only performed when exhale is invoked with the -e option. This includes rescinded files.
Files created in the master since the previous base release are simply copied to the archive.
Instead of switching exhale off during this period, it may continue to be run in latchkey mode. Latchkey mode is terminated as soon as exhale is invoked without the -l option, even if there are no files to be updated. The following aips2mgr cron entry runs exhale at 0630 and 1830 each night in Socorro. Newly created directories are not propagated if they don't contain newly created files.
