+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].
+
+    \param -tri \n
+    Triangulate surface.
