+Class
+    Foam::timeActivatedExplicitMulticomponentPointSourceNew
+
+Description
+    Provides a mechanism to introduce point sources to a set of carrier fields.
+    Carrier fields are supplied on consruction, and interrogated to provide the
+    field indices of the sources.
+
+    Properties are described in a <sourceName>Properties dictionary, e.g.:
+
+    active          true;       // are sources active (true/false)
+
+    pointSources
+    (
+        source1                 // source name
+        {
+            timeStart           0.0;
+            duration            1.0;
+            location            (0 0 0);
+            fieldData
+            (
+                (H2O            0.1)
+                (O2             0.05)
+            );
+        }
+        source2                 // source name
+        {
+            timeStart           0.5;
+            duration            2.0;
+            location            (1 1 1);
+            fieldData
+            (
+                (NO             0.1)
+                (CO2            0.05)
