+=head1 NAME
+
+Test2::Compare::Pattern - Use a pattern to validate values in a deep
+comparison.
+
+=head1 DESCRIPTION
+
+This allows you to use a regex to validate a value in a deep comparison.
+Sometimes a value just needs to look right, it may not need to be exact. An
+example is a memory address that might change from run to run.
