# 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.
