seeing what is the prover up to (for advanced users)
Major Section:  PSTACK

General Forms:
(verbose-pstack t)   ; get trace-like information on prover during proofs
(verbose-pstack '(fn1 fn2 ...))
                     ; as above, but omit calls of the indicated functions
(verbose-pstack nil) ; turn off trace-like information on prover
For example, (verbose-pstack '(ev-fncall)) will provide a trace of various prover functions during proofs, except for the function ev-fncall.

By evaluating (verbose-pstack t) one can get trace-like information during subsequent proofs about prover functions, including time summaries, printed to the screen during a proof. To turn off this feature, evaluate (verbose-pstack nil). Also See pstack.
