+# LuaRocks package infrastructure
+# see http://luarocks.org/
+#
+# This file implements an infrastructure that eases development of
+# package .mk files for LuaRocks packages.
+# LuaRocks supports various build.type : builtin, make, cmake.
+# This luarocks infrastructure supports only the builtin mode,
+# the make & cmake modes could be directly handled by generic & cmake infrastructure.
+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this LuaRocks infrastructure requires
+# the .mk file to only specify metadata informations about the
+# package: name, version, etc.
+#

+# generate the necessary make targets
+#
+#  argument 1 is the lowercase package name
+#  argument 2 is the uppercase package name, including an HOST_ prefix
+#             for host packages

+#             for host packages
+#  argument 4 is the package directory prefix
