define Package/protobuf-compat/description/Default
Protocol Buffers are a way of encoding structured data in an efficient
yet extensible format. Google uses Protocol Buffers for almost all of its
internal RPC protocols and file formats.
endef
define Package/protobuf-compat/description
$(call Package/protobuf-compat/description/Default)
This package provides the libprotoc, libprotobuf, and libprotobuf-lite
libraries. For a much smaller protobuf package, see
"protobuf-compat-lite".
