114    =item DBD
115    
116    Name of the DBD file. If specified, the DBD must be in the main FIG directory
117    (specified in C<$FIG_Config::fig>). This option allows the use of an alternate
118    DBD during load, so that access to the database by other processes is not
119    compromised.
120    
121    =item loadDirectory
122    
123    Directoty containing the load files. This option allows you to request that
124    load files from another version of the NMPDR be used, which is useful when
125    creating a new NMPDR: we can yank in the data from the previous database while
126    waiting for the new load files to be generated.
