# The project pulls together source from a wide variety of places,
# so while the license of the combined work is declared to be
# BSD-3-Clause, there is actually a huge set of licenses to track
#
# While this package contains pre-built signed enclaves, upstream
# has a reproducible build process to create unsigned enclaves.
# This license list is determined from analyzing that build
# which is equivalent to the pre-bult binaries, without a sig.
