Given that the packaging infrastructure (julia-pkg-dev) is not ready,
the FactCheck package will have to be modified at a later stage, when
julia-pkg-dev is ready. So there is some duplicate work involved here.
Especially I don't want people to take inspiration from that example,
because it would mean even more work when julia-pkg-dev is ready.

However, I don't want to discourage you from contributing to the team.
So if you want to package FactCheck now, please name it julia-factcheck,
and set the Debian Julia Team in the Maintainer field. 

Concerning the location of the files, what I said in my previous email
was wrong. They should go in /usr/share/julia/site/FactCheck/. Note that
there is no Julia version number in that path. It is because I have
patched Julia to remove that version number (see
unversioned-system-load-path.patch). The reason is that such a version
number is silly, because it would force us to recompile all Julia
packages at every new Julia version. This is a waste of time and effort,
especially for arch:all packages which need sourceful uploads. The
drawback is that FactCheck will not be seen by non-Debian julia
installations, but I consider this as relatively minor. Maybe we should
discuss that with upstream.

Also, I have accepted your request to join the Team. Welcome!
