"raise Fail" for internal errors + one new internal error (instead of "Match")

make test work again (broken since 09467cdfa198?)

adjust Nitpick example to follow latest wave of renamings

proper polymorphic Skolemization of uncached facts + synchronization of caching and relevance filter

beta-eta-contract, to respect "first_order_match"'s specification; Sledgehammer's Skolem cache sometimes failed without the contraction

adjust Nitpick's handling of "<" on "rat"s and "reals"

remove needless variables

hide sum explicitly

merged

adjust popular symbolic type constructors

tailored set of code equations manually

tuned quotes, antiquotations and whitespace

moved inductive_codegen to place where product type is available; tuned structure name

qualified type "*"; qualified constants Pair, fst, snd, split

tuned quotes, antiquotations and whitespace

qualified types "+" and nat; qualified constants Ball, Bex, Suc, curry; modernized some specifications

Adapted Mirabelle script (cf. f60e4dd6d76f)

merged

more consistent naming aroud type classes and instances

back to non-release mode;

removed obsolete test tags;

Added tag Isabelle2009-2 for changeset 35815ce9218a

final tuning;

NEWS: IsabelleText font;

Pretty.string_of (in Scala): actually observe margin/metric;

tuned Command.toString -- preserving uniqueness allows the Scala toplevel to print Linear_Set[Command] results without crashing;

tuned tooltips;

obsolete;

explicit treatment of empty exception block, which could lead to confusing output (e.g. in the theory loader), or even prevent error output altogether;

contrib/README;

removed outdated/confusing INSTALL file;

clarified font_family vs. font_family_default; install_fonts: refrain from any magic that does not really work on Mac OS, but introduces strange problems on other platforms;

disable set_styles for now -- there are still some race conditions of PropertiesChanged vs. TextArea painting (NB: without it Isabelle_Token_Marker will crash if sub/superscript is actually used);

Added tag isa2009-2-test2 for changeset dfca6c4cd1e8

more uniform treatment of options and attributes, preferring formal markup over old-style LaTeX macros;

merged;

Tuned.

Documented changes in induct, cases, and nominal_induct method.

made SML/NJ happy again;

recovered some untested theories;

proper target directory;

renaming

show more respect for user-specified facts, even if they could lead to unsound proofs + don't throw away "unsound" theorems in "full_type" mode, since they are then sound

fix remote Vampire diagnosis

make Sledgehammer's "add:" and "del:" syntax work better in the presence of aliases; some of these aliases pop up only after Sledgehammer has converted the formula to CNF, so it can be very confusing to the user who said "add: foo del: bar" that "bar" is used in the end.

totally bypass Sledgehammer's relevance filter when facts are given using the "(fact1 ... factn)" syntax; faster and more reliable
