+Trait to allow support of different psr/http-message versions.
+
+Based on the psr-log-aware-trait, developed by Matěj Humpál, K Widholm and Mark Dorison.
+
+By including this shim, you can allow composer to resolve your Psr\Http\Message version for you.
+

+from the Mpdf\HttpMessageShim namespace.
