2010-08-11 Christian Urban 2010-08-11 deleted duplicate lemma
2010-07-28 wenzelm 2010-07-28 use file names relative to master directory of theory source -- Proof General can now handle that due to the ThyLoad.add_path deception (cf. 3ceccd415145);
2010-06-29 Christian Urban 2010-06-29 separated the lifting and descending procedures in the quotient package
2010-06-28 Cezary Kaliszyk 2010-06-28 Quotient package reverse lifting
