NAME

binsearchaperl - binary search perl versions that exhibit changing behaviour

SYNOPSIS

 binsearchaperl --bounds 17000-18000 --prog testscript.pl --build
 binsearchaperl --h

DESCRIPTION

This script is built upon the buildaperl script and the Perl::Repository::APC module and All Perl Changes . You pass it a interval of patch numbers and a test script that exhibits some change in the behaviour of perl. The script then does a binary search to determine when exactly the change in behaviour occurred. It then stops.

The --h option displays all available options.

The most convenient setup to run this script is just the same as described in the buildaperl manpage.

Test programs are ideally written in a simple style that outputs "ok" or "not ok", but you did know that already.
