   104
   the ATPs are run in parallel. The "real" component gives the faction of the

   105
   time available given to the slice and should add up to 1.0. The first "bool"
blanchet@42723
   106
   component indicates whether the slice's strategy is complete; the "int", the
blanchet@43569
   107
   preferred number of facts to pass; the first "string", the preferred type
blanchet@45521
   108
   system (which should be sound or quasi-sound); the second "string", the
blanchet@46409
   109
   preferred lambda translation scheme; the second "bool", whether uncurried
blanchet@46409
   110
   aliased should be generated; the third "string", extra information to
blanchet@45521
   111
   the prover (e.g., SOS or no SOS).
blanchet@42723

blanchet@42723

   The last slice should be the most "normal" one, because it will get all the

   time available if the other slices fail early and also because it is used if
blanchet@43569
