 * 5.10 Can I import an existing surface mesh in Gmsh and use it to
 build a 3D mesh?
 
-Yes, either in the form of a STL triangulation, or FIXME: TODO
+Yes, see for example 'demos/sphere-discrete.geo'. Note that Gmsh
+does not currently modify the surface mesh that you provide in this 
+way, so this surface mesh has to be conform (without gaps, hanging 
+nodes, etc.) and must contain surface elements having the final
+desired sizes.

+Gmsh can also import discrete geometries in the form of STL 
+triangulations, and remesh these to respect certain constraints. This
+is an experimental and undocumented feature as of this writing
