+# Meson package infrastructure
+#
+# This file implements an infrastructure that eases development of
+# package .mk files for Meson packages. It should be used for all
+# packages that use Meson as their build system.
+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this Meson infrastructure requires
+# the .mk file to only specify metadata information about the
+# package: name, version, download URL, etc.
+#
+# We still allow the package .mk file to override what the different
+# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
+# already defined, it is used as the list of commands to perform to
+# build the package, instead of the default Meson behaviour. The
+# package can also define some post operation hooks.
+#

+# inner-meson-package -- defines how the configuration, compilation and
+# installation of a Meson 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)
