+Application
+    foamToSurface
+
+Description
+    Reads an OpenFOAM mesh and writes the boundaries in a surface format.
+
+Usage
+    - foamToSurface [OPTION] \n
+    Reads an OpenFOAM mesh and writes the boundaries in a surface format.
+
+    @param -scale \<factor\>\n
+    Specify an alternative geometry scaling factor.
+    Eg, use @b 1000 to scale @em [m] to @em [mm].
