# The makefile looks like it tries to invoke ocamlfind but only if DESTDIR
# isn't set. If it is set (which it is) LIBINSTALLDIR must be set too
# for installing opam-installer metadata.

# However it looks like some (extra) documentation gets
# installed in the wrong place so... delete it.

# It seems that some tests fail under mock.
# I am not sure why at the moment. So for now I'll just turn them off.

# Upstream puts this documentation under opam-installer, not opam.
# Since I have opam require opam-installer anyway, this seems reasonable.
# (And there are lots of man pages in the opam package, so it has docs).
