I have a mesh in the dolfin format. Is there a way for me to export it to the gmsh format? I'm aware of this old post: https://fenicsproject.org/qa/959/how-to-save-a-mesh-in-gmsh-format. However, I was unable to install the required octave package (msh) and I don't think that I will be able to unless I modify the package's code as it has not been updated since 2014! In particular, the code still uses boost's shared pointers instead of those of the standard library, but Dolfin switched from the former to the latter in 1.3 (For a similar, but fixed issue: https://lists.gnu.org/archive/html/help-octave/2017-03/msg00224.html).
