-# 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.

+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this generic infrastructure requires the

+#   1. Metadata informations about the package: name, version,
+#      download URL, etc.
+#
+#   2. Description of the commands to be executed to configure, build
