+# @BLURB: Provide a set of functions to build nginx dynamic modules.
+# @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+=

+# Uses version cut of the first three parts of the version to determine the proposed nginx version.
+# This version is used for SRC_URI, BDPEND and compiling process.
