@echo off
rem A batch program to build PGO (Profile guided optimization) by first
rem building instrumented binaries, then running the testsuite, and
rem finally building the optimized code.
rem Note, after the first instrumented run, one can just keep on
rem building the PGUpdate configuration while developing.
