+			From after 2.3.1, until 3.0.0 the script pcb-rnd-src needs to be sourced
+			before executing pcb-rnd from source, if there is no system-wide librnd
+			installation available. The whole process of running pcb-rnd without
+			installation should be:
+			<ul>
+				<li> cd src
+				<li> . ./pcb-rnd-src
+				<li> ./pcb-rnd
+			</ul>
