+# Generic package infrastructure
+#
+# This file implements an infrastructure that eases development of
+# package .mk files. It should be used for all non-autotools based
+# packages. Autotools-based packages should use the specialized
+# autotools infrastructure in package/Makefile.autotools.in.
+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this generic infrastructure requires the
+# .mk file to specify:
+#
+# 1. Metadata informations about the package: name, version,
+# download URL, etc.
+#
+# 2. Description of the commands to be executed to configure, build
+# and install the package
+#
+# The autotools infrastructure specializes this generic infrastructure
+# by already implementing the configure, build and install steps.
