+# @BLURB: Provide a set of functions to build nginx dynamic modules.
+# @DESCRIPTION:
+# Eclass to make dynamic nginx modules.
+# As these modules are built against one particular nginx version.
+# The nginx version is encoded in PV as the first three version components,
+# while the rest of PV represent's the module's upstream version.
+#
+# To build an nginx module the whole nginx source code is needed.
+# Therefore SRC_URI is set to the nginx source archive.
+# Ebuilds using this eclass thus must use SRC_URI+= instead of
+# SRC_URI=.
