+If this environment variable is set, L<Test::Leaner> will replace its functions by those from L<Test::More>.
+Moreover, the symbols that are imported you C<use Test::Leaner> will be those from L<Test::More>, but you can still only import the symbols originally defined in L<Test::Leaner> (hence the functions from L<Test::More> that are not implemented in L<Test::Leaner> will not be imported).
+If your version of L<Test::More> is too old and doesn't have some symbols (like L</note> or L</done_testing>), they will be replaced in L<Test::Leaner> by croaking stubs.
+
+This may be useful if your L<Test::Leaner>-based test script fails and you want extra diagnostics.
