 * 5.10 Can I import an existing surface mesh in Gmsh and use it to
 build a 3D mesh?
 
-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

+Yes, see for example 'demos/sphere-discrete.geo'. You can either use
+the surface mesh "as-is" (for example to build a 3D mesh from an
+existing boundary mesh), or you can remesh the surfaces to respect

 * 6.3 Can I launch Gmsh from my solver (instead of launching my solver
 from Gmsh) in order to monitor a solution?
 
-Sure. A simple C program showing how to do this is given in
-'utils/misc/callgmsh.c'.

-* 6.4 Is it possible for Gmsh top listen to an external program not

-Yes: just create a program as described in 6.1 above (you can skip the

+Sure. The simplest (but rather crude) approach if to re-launch Gmsh
