1997-06-23 paulson 1997-06-23 Removal of structure Context and its replacement by a theorem list of congruence rules for use in CONTEXT_REWRITE_RULE (where definitions are processed)
1997-06-05 paulson 1997-06-05 Numerous simplifications and removal of HOL-isms Addition of the "simpset" feature (replacing references to \!simpset)
1997-06-03 paulson 1997-06-03 More de-HOLification: using Free, Const, etc. instead of mk_var, mk_const Changed the TFL functor to a structure (currently called Prim)
1997-05-26 paulson 1997-05-26 Now checks the name of the function being defined; More de-HOL-ification
1997-05-22 paulson 1997-05-22 New headers and other minor changes
1997-05-20 paulson 1997-05-20 Removal of redundant code (unused or already present in Isabelle. This eliminates HOL compatibility but makes the code smaller and more readable
1997-05-15 paulson 1997-05-15 TFL now integrated with HOL (more work needed)
