Hi Ludo,

Many thanks for your review.  I attach the revised patch.

'git-fetch' it is.  There is a clone-via-https option for OpenCASCADE
so I have updated the 'origin' section accordingly.

Not in this case, AFAICS.  There is a test system that is accessible
after installation, via a shell script, so I have included a comment
and a link to the documentation for that.

This version of OpenCASCADE is the upstream version.  In recent times
it has been updated more regularly than the oce version.

Best regards,

Paul.
