Here's my rough preprocessor concept. It doesn't understand ruleset
files, but it can output them from Python dicts. You probably need
Python 2.4 to run this. Here's an example:

# input
rules_1 = {
    'effect_martial_law_each': {
        'name': 'Martial_Law_Each',
        'value': 1,
        'reqs': OR(dict(type='Gov', name='Anarchy', range='Player'),
                    dict(type='Gov', name='Despotism', range='Player'),
                    dict(type='Gov', name='Monarchy', range='Player'))
    }
}

freeciv_formatter(expand_rules(rules_1))

# output

[effect_martial_law_each_000]
name = Martial_Law_Each
reqs = { "range", "type", "name"
        "Player", "Gov", "Anarchy"
}
value = 1

[effect_martial_law_each_001]
name = Martial_Law_Each
reqs = { "range", "type", "name"
        "Player", "Gov", "Despotism"
}
value = 1

[effect_martial_law_each_002]
name = Martial_Law_Each
reqs = { "range", "type", "name"
        "Player", "Gov", "Monarchy"
}
value = 1
