# Generic package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files. It should be used for packages that do not rely
# on a well-known build system for which Buildroot has a dedicated
# infrastructure (so far, Buildroot has special support for
# autotools-based and CMake-based packages).
#
# 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
