```{index} single: ExtUtils::testlib ``` # ExtUtils::testlib add blib/\* directories to @INC ## SYNOPSIS ```perl use ExtUtils::testlib; ``` ## DESCRIPTION After an extension has been built and before it is installed it may be desirable to test it bypassing `make test`. By adding ```perl use ExtUtils::testlib; ``` to a test program the intermediate directories used by `make` are added to @INC.
