I believe the problem is upstream of the machine I control. I'll see what I can do.

The easy targets being done now are mostly things that I believe would need
to be done regardless of the eventual strategy, be it a) do nothing b) make
the existing system suck less c) replace the parsers and keep the rules
d) replace everything. For any of these strategies to be successful you would
need to start with a clean clear and consistent rules corpus.
Remember how people were complaining that ESR couldn't prove that the CML2
rules corpus did the same things as the CML1 rules corpus? One of the
reasons was that the CML1 rules corpus is so screwed that's its impossible
for either a human or a machine to figure out what was supposed to happen
and whether what was actually happening was deliberate.
Roman, I believe the exactly same issue will apply to your config system
too, because it uses a machine translation step from CML1. GCML2's syntax
checker started life as a CML1-to-CML2 converter (inspired by your work), but
I gave up on machine translating because it would be GIGO.
This is why I'm not talking about replacing shell based parsers yet. First
we need to get a rules corpus for which it is possible to create a parser
which can parse cleanly, consistently, and correctly.
