-- Installing tikz is a bit tricky because there are many packages involved and it's
-- sort of impossible to derive from the names what to include in the installation.
-- I tried to use the ctan scrips we ship but there is no way to reliably derive a
-- set from the topics or packages using the web api (there are also some
-- inconsistencies between the jkson and xml interfaces that will not be fixed). A
-- wildcard pull of everything tikz/pgf is likely to fail or at least gives files we
-- don't want and/or need, the solution is to be specific.
--
-- We use curl and not the built in socket library because all kind of ssl and
-- redirection can kick in and who know how it evolves.
--
-- We use the context unzipper because we cannot be sure if unzip is present on the
-- system. In many cases windows, linux and osx installations lack it by default.
--
-- This script has no help info etc as it's a rather dumb downloader. One can always
-- do a better job than this suboptimal quick hack. Let me know if I forget to wipe
-- something.
