2013-08-13 wenzelm 2013-08-13 standardized symbols via "isabelle update_sub_sup", excluding src/Pure and src/Tools/WWW_Find;
2011-09-21 blanchet 2011-09-21 reintroduced Minipick as Nitpick example
2011-04-04 krauss 2011-04-04 raised timeouts further, for SML/NJ -- because of variations in machines/compilers, fixed timeouts can merely prevent non-termination, not enforce particular performance characteristics.
2010-12-19 blanchet 2010-12-19 added a timestamp to Nitpick in verbose mode for debugging purposes; turn on verbose mode for the examples
2010-11-03 blanchet 2010-11-03 standardize on seconds for Nitpick and Sledgehammer timeouts
2010-04-25 blanchet 2010-04-25 remove "skolemize" option from Nitpick, since Skolemization is always useful
2010-02-23 blanchet 2010-02-23 improved precision of small sets in Nitpick
2010-02-22 blanchet 2010-02-22 enabled Nitpick's support for quotient types + shortened the Nitpick tests a bit
2010-02-09 blanchet 2010-02-09 optimization to quantifiers in Nitpick's handling of simp rules + renamed some SAT solvers
2010-02-05 blanchet 2010-02-05 added hotel key card example for Nitpick, and renumber atoms in Nitpick's output for increased readability
2009-12-18 blanchet 2009-12-18 polished Nitpick's binary integer support etc.; etc. = improve inconsistent scope correction + sort values nicely in output + handle "mod" using the characterization "x mod y = x - x div y * y" (instead of explicit code in Nitpick) + introduce KK = Kodkod as abbreviation
2009-12-17 blanchet 2009-12-17 added support for binary nat/int representation to Nitpick
2009-12-14 blanchet 2009-12-14 make Nitpick tests more robust by specifying SAT solver, singlethreading (in Kodkod, not in Isabelle), and higher time limits
2009-11-17 blanchet 2009-11-17 fixed "expect" of Nitpick examples to reflect latest changes in Nitpick
2009-10-23 blanchet 2009-10-23 continuation of Nitpick's integration into Isabelle; added examples, and integrated non-Main theories better.
