+A directory of tools provided to people using CVS Bison. None of |
+these is distributed. |

+* bench.pl |
+A primitive Perl script to run benches. Currently its only bench is |
+the usual calculator: it has a lightweight processing part (but not |
+null), so it is really emphasizing the cost of the whole parsing |
+(including scanning and I/O). |
+ |
+Set the envvars BISON and CC to the programs and flags you want to |
+use. They default to bison and gcc. To run a non-installed bison |
+from a tarball built in _build, I suggest the following. |
+ |
+ BISON=_build/tests/bison CC='gcc -O2' ./bench.pl |
+ |
+(The _build/tests/bison wrapper makes sure that _build/src/bison will |
+use the tarballs' skeletons, not those already installed as a |
+straightforward use of _build/src/bison would.) |
