+## @file
+## @brief SMTP Developer Makefile.
+## @author James Humphrey (mail@somnisoft.com)
+## @version 0.99
+##
+## This Makefile used internally to build and test the SMTP client library.
+## Do not use this Makefile for building the library into your application.
+## Instead, include the src/smtp.h and src/smtp.c directly into your project
+## and add those files as part of your own build system.
+##
+## This software has been placed into the public domain using CC0.
