DESCRIPTION

This module traps all warnings and summarizes them when the your perl script exits. Warning trapping can be interrupted and resumed by removing/installing the Devel::SummarizedWarnings::append_to_warning_log handler into $SIG{'__WARN__'}.

Trapped warnings are stored in @Devel::SummarizedWarnings::LOGGED_WARNINGS.
