# Native libraries built as part of the rust build process
#
# This portion of the rust build system is meant to keep track of native
# dependencies and how to build them. It is currently required that all native
# dependencies are built as static libraries, as slinging around dynamic
# libraries isn't exactly the most fun thing to do.
#
# This section should need minimal modification to add new libraries. The
# relevant variables are:
#
#   NATIVE_LIBS
#	This is a list of all native libraries which are built as part of the
#	build process. It will build all libraries into RT_OUTPUT_DIR with the
#	appropriate name of static library as dictated by the target platform
#
#   NATIVE_DEPS_<lib>
#	This is a list of files relative to the src/rt directory which are
#	needed to build the native library. Each file will be compiled to an
#	object file, and then all the object files will be assembled into an
#	archive (static library). The list contains files of any extension
#
# If adding a new library, you should update the NATIVE_LIBS list, and then list
# the required files below it. The list of required files is a list of files
# that's per-target so you're allowed to conditionally add files based on the
# target.
