It's a "dashboard" which displays submitted test results. It can be
used to aggregate testing on multiple platforms. is the dashboard for
CMake itself.

Boost could potentially use it, either the open dashboard or a
self-hosted one, but it's strictly optional. Maybe Travis is
sufficient, or you could integrate something else entirely.

Last time I tried it, it was inferior to the native packaging tools.
Particularly when packaging libraries, it didn't do as good a job with
library version dependencies--if you build Debian packages on a
non-Debian platform it can't compute the minimum library version from

I think it's primarily useful for packaging standalone applications
where there are no complex library dependencies. Certainly for Windows
and MacOS X it makes sense. For packaging a set of libraries like
Boost, I don't think it's as useful; we already have good Boost
packaging anyway, so I'd suggest ignoring it at least for now.
