Mon, 28 Nov 2011 17:05:41 +0100 wenzelm avoid stepping outside of context -- plain zero_var_indexes should be sufficient;
Thu, 24 Nov 2011 21:01:06 +0100 wenzelm modernized some old-style infix operations, which were left over from the time of ML proof scripts;
Mon, 08 Aug 2011 17:23:15 +0200 wenzelm misc tuning -- eliminated old-fashioned rep_thm;
