In my opinion, OPTIONS should be static; it should represent the default
feature set the maintainer or the software author has/had in mind (that
is why I do not consider it to be a problem when OPTION's datafile is
not read in the BATCH and PACKAGE_BUILDING cases because you just have
to get the parser right, instrumenting the fact that you get a
WITHOUT_FOO for every WITH_FOO for free). Autotuning this default option
set can have interesting effects in a package building environment,
effectively it forces you to build every package in a clean room
environment to avoid dependency pollution.
