HOL4_{YICES,Z3}_EXECUTABLE evaluated at run-time (as opposed to compile time). Minor refactoring.

Made location of Yices and Z3 executables configurable. This allows to work around issue #87.

Tjark Weber <Tjark.Weber@cl.cam.ac.uk> |
Added -file: to the Z3 command line (to simplify external post-processing, in particular for Z3 under Wine).

Tjark Weber <Tjark.Weber@cl.cam.ac.uk> |
Added support for LET terms to the SMT-LIB translation. (Proof reconstruction for Z3 still requires unfolding of LETs.)

Tjark Weber <Tjark.Weber@cl.cam.ac.uk> |
Major update, adding a translation from HOL to SMT-LIB 2 and enabling Z3 proof checking again. (The latter still has some quirks, because Z3's proof syntax is not fully SMT-LIB 2 compliant.)

Tjark Weber <Tjark.Weber@cl.cam.ac.uk> |
Major update, adding support for Z3 2.11 proofs (SMT-LIB 2 format). Note that this breaks Z3 proof checking from HOL4 (for now), as no translation from HOL4 into SMT-LIB 2 has been implemented yet.

Temporary files are now created in the temporary directory (i.e., /tmp on Unix) and no longer re-used between separate SMT solver invocations.

Simplified the interface to provide tactics only (use Tactical.TAC_PROOF or similar to derive functions of type goal -> thm). Also simplified the discharging of definitions in theorems derived by Z3.

Changed the interface to take a goal (i.e., a pair of assumption list and conclusion) instead of a single term. The same interface is provided by the SMT-LIB standard, which distinguishes between assumptions and query formulas, and claims that "many SMT solvers can process assumptions more efficiently if they are explicitly identified as such." I don't know if that's true, but in any case, identifying them explicitly is what we do now.

This is a major update, adding proof reconstruction for Z3 (and several smaller improvements).
