+Class
+    Foam::scalarTransport
+
+Description
+    This function object evolves a passive scalar transport equation.  The
+    field in ininitially zero, to which sources are added.  The field name
+    is assigned the name of the function object.  Boundary conditions are
+    automatically applied, based on the velocity boundary conditions.
+
+    - the field can be zeroed on start-up using the resetOnStartUp flag
+    - to employ the same numerical schemes as the flow velocity, use the
+      autoSchemes flag
+    - the diffusivity can be set manually using the DT entry, or retrieved
+      from the turbulence model (if applicable)
