the debian packaging scripts modify the package data:

  $(if $(HASKELL_HIDE_PACKAGES),sed -i 's/^exposed: True$$/exposed: False/' $$pkg_config;) \

and also parses data from not-yet registered package files, and I think
it also changes paths somewhere. For all that plumbing stuff, human
readable file formats are very convenient.
