more direct loose_bvar1;
2011-03-24, by wenzelm
indentation;
2011-03-24, by wenzelm

added editor mode line;
2011-03-23, by wenzelm
isolate change of Proofterm.proofs in TPTP.thy from rest of session;

add ring_of_sets and subset_class as basis for algebra
2011-03-22, by hoelzl
added first-order TPTP version of Nitpick to Isabelle, so that its sources stay in sync with Isabelle and it is easier to install new versions for SystemOnTPTP and CASC -- the tool is called "isabelle nitrox" but is deliberately omitted from the tool list unless the component is explicitly enabled, to avoid clutter
2011-03-22, by blanchet
added "TPTP" theory with IsabelleP tactic, so that it is maintained alongside with Isabelle and that the CASC version of Isabelle is provided by Isabelle itself instead of being stored on the TPTP servers
2011-03-22, by blanchet
remove lie from documentation
2011-03-22, by blanchet

2011-03-22, by wenzelm

let syntax: reverted to plain "id", since translations cannot cope with constraints (notably position information);
2011-03-22, by wenzelm

2011-03-22, by wenzelm
tuned indendation and parentheses;
2011-03-22, by wenzelm
