/** @title The LOL policy @author Kaarel Kaljurand @version 2008-01-30

This is based on the if-then sentences in Appendix A in "Further Notes. Draft of December 19, 2007" by Juri Luca De Coi.

The idea has been to convert Juri's if-then sentences into every-sentences to see if they come out more readable than the if-then sentences, and also to test the Core ACE paraphraser which would translate the every-sentences back into if-then sentences. This way we will have 3 sets of sentences: Juri's original sentences, Kaarel's "everyfication", DRACE Core's paraphrases. We should make sure that APE really converts them into equivalent DRSs. We should also make sure that Protune users accept those 3 sets as equivalent.

Note: the sentences below can be parsed with guessing on. On 2007-12-30, the roundtrip ACE1->DRS->ACE2->DRS worked, where ACE1 is this file, DRS is its DRS-translation, ACE2 is the Core ACE paraphrase of ACE1, and DRS (i.e. the same DRS as before) is its DRS-translation. */
