<description>The property file (for a standalone database instance) or the
10+
jini configuration file (for a federation). The file MUST end with either
11+
".properties" or ".config". This path is relative to the directory from
12+
which you start the servlet container so you may have to edit it for your
13+
installation, e.g., by specifying an absolution path. Also, it is a good
14+
idea to review the RWStore.properties file as well and specify the location
15+
of the database file on which it will persist your data.
16+
17+
Note: You MAY override this parameter using
18+
"-Dcom.bigdata.rdf.sail.webapp.ConfigParams.propertyFile=FILE"
19+
when starting the servlet container.
