# 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 information about the
# package: name, version, etc.

# inner-luarocks-package -- defines how the configuration, compilation and
# installation of a LuaRocks package should be done, implements a few hooks to
# tune the build process and calls the generic package infrastructure to
# generate the necessary make targets
#
#  argument 1 is the lowercase package name
#  argument 2 is the uppercase package name, including a HOST_ prefix
#             for host packages
#  argument 3 is the uppercase package name, without the HOST_ prefix
#             for host packages
#  argument 4 is the type (target or host)
