I'm confused. I interpreted this as meaning that, if I added a Save 
command to the end of my .geo file, then the 3-D mesh would 
automatically be written out after it was created. This didn't
happen when I tried it.

I'm also confused about 2 statements in gmsh.html. On the one hand, in 
6.3 it says 'The actual mesh "actions" ... cannot be specified in the 
script files.' On the other hand, in 6.3.3 it says that the 'Mesh 
expression;' command 'Generates expression-D mesh'. These 2 statements 
seem to be contradictory. What am I missing?

Thanks.
