# built on multiple different platforms (linux, mac, windows), which makes
# it difficult to support a local build of the nuget.
# To allow simple local builds (restricted to a single platform),
# we provide a way of building "partial" nugets that only include artifacts
# that can be built locally on a given platform (e.g. linux), and
# contain placeholders (empty files) for artifacts that normally need
# to be built on a different platform. Because such nugets obviously
# only work on a single platform (and are broken on other platform),
# whenever we are building such nugets, we clearly mark them as
# "singleplatform only" to avoid mixing them up with the full "multiplatform"
# nugets by accident.
