# The '-skip_odb' option is currently an undocumented feature, though it will be
# documented in a future release (pending a separate change to normalize command
# line processing to add '-h' and '-man' options across all key scripts).  If
# '-skip_odb' is specified, the live checkpoint of files in P4ROOT is created
# per usual, but the replay of the newly generated checkpoint to the offline_db
# is skipped.  If this option is used, instructions are provided to use the
# recreate_offline_db.sh script to do the rebuild later.
