Bug#898622: ITP: mat2 -- Metadata Anonymisation Toolkit 2

[intrigeri <intrigeri@debian.org>]

Hi!

For the record we've started some discussion upstream about the
relationship between MAT and MAT2 / the future of MAT v1.

Personally I don't have anything at stake wrt. what's decided
upstream, although I've already shared my thoughts with
Julien privately.

What matters to me is the users' perspective. I think we should
provide a clear, unambiguous transition path and avoid leaking
technical details to users. So once MAT2 reaches feature parity with
MAT (I think the only real blocker is the lack of a Nautilus
extension; MAT v1's seems to be broken on sid currently but it has
a GUI which mitigates that problem) I think we should:

 - Have mat2 conflicts+replaces mat, remove mat from testing+sid,
   and ship a transitional package called mat that pulls mat2 in.
   Or simply call mat2 source and binary packages "mat".

 - Ensure the app launcher (.desktop) for MAT2 makes it clear that it
   provides MAT, without leaking version numbers or such:

     GenericName=Metadata Anonymisation Toolkit
     Name=MAT

Thoughts?

Cheers!
