[Gmsh] Newbie question

[Karen Pease]

I greatly appreciate that.  However, I just tried it and (shouldn't be
surprised by now) it doesn't work either.  Downloaded from the download
link on the Onelab website and installed it, and in the command line I
get:

[meme at fwiffo gmsh-getdp-Linux64]$ ./onelab.py  
./onelab.py: line 28:

./onelab.py: line 31: _VERSION: command not found

./onelab.py: line 33: syntax error near unexpected token `('

./onelab.py: line 33: `def path(dirname, inp):'


For a short period, the cursor turns into a crosshairs... but after
clicking around for a while it crashes out, as per above (starting with
the _VERSION line).  A window never appears.

As for the models in the Onelab directory, none of them are STLs, or
any other format that Blender can export - they're .dat, .geo and .pro.
