+In recent versions of Freeciv, Rivers are no longer a separate type \
+of terrain.  Now, any terrain (except Ocean) may have a River on \
+it.  A River adds 1 trade to the resources produced by that tile.  \
+It also increases a tile's defense factor by 50%.  Finally, land \
+units may move along a River (but not diagonally); movement along a \
+River costs only 1/3 of a movement point.\
