[Incubator] Bezitopo and PerfectTIN

[Jody Garnett]

Greeting Pierre, thanks for joining this email list.

Can I ask for two things:
- your osgeo user id, you can create one here
- links to the source code repository

We have three stages at osgeo to support free/open geospatial software:

1) OSGeo website, run by the marketing committee but we check the software
project
2) OSGeo Community program, run by the osgeo board but we check the
software project
3) OSGeo Project (as a full fledged committee, run by the osgeo board but
we work with the project team to meet the requirements)

For the above we tend to focus on the people/team and view this as an
outreach/advocacy activity. Given your very complete description you are
already well aware of how open source software works.
