+# @DESCRIPTION:
+# Eclass to make dynamic nginx modules.
+# As these modules are hardly build against one nginx version we use version
cut to indicate the nginx version too.
+# The first three parts of the version must represent the nginx version,
+# the remaining part displays the module version.
+#
+# To build a nginx module the whole nginx source code is needed,
+# therfore we set the SRC_URI to the nginx source archive.
+# The module archive must be added with SRC_URI+=
