Marco the mesh format used by the msh package is extremely simple and is 
described 
here in detail for 2D:

http://octave.sourceforge.net/msh/function/msh2m_structured_mesh.html

and here for 3D

http://octave.sourceforge.net/msh/function/msh3m_structured_mesh.html

essentially it is just an Octave structure with 3 matrix fields: 

p is the list of vertices
t is the connectivity matrix
e is the list of boundary facets

if you find that documentation unclear I'd be very glad to accept you patches 
to make more
clear and to provide guidance in helping you prepare those patches.

yes msh is the only currently available mesh managing package I am aware of 
and it is part of Octave-Forge, not Octave.
