| markers, which will be replaced by the corresponding hash or date: | ||
| @MYSQL_GIT_HASH@ | ||

| @ROCKSDB_GIT_HASH@ | ||
| @ROCKSDB_GIT_DATE@ | ||
| =item B<--mysql_githash> | ||
| Optional git hash for the MySQL repository. If this is not specified the | ||

| dates is supplied, all of them must be supplied. | ||
| =item B<--mysql_gitdate> | ||
| Optional git date for the MySQL repository. If this is not specified the | ||
| script will use "git log" to query the repository. If one of the hashes or | ||
| dates is supplied, all of them must be supplied. | ||
| =item B<--rocksdb_githash> | ||
| Optional git hash for the RocksDB repository. If this is not specified the | ||
| script will use "git log" to query the repository. If one of the hashes or | ||
| dates is supplied, all of them must be supplied. | ||
| =item B<--rocksdb_gitdate> | ||
| Optional git date for the RocksDB repository. If this is not specified the | ||
