# The source distfile is a gclient checkout of the release tag without the
# prebuilt Linux toolchains. The bootstrap is a FreeBSD build of the Dart
# SDK, used to run the Dart parts of the build. Both are made with the tools
# in https://github.com/pattems/dart-sdk-freebsd: tools/make-dist.sh for
# the source, and docs/bootstrap.md describes the bootstraps.

# Perfetto is off by default on FreeBSD; the patch-third__party_perfetto_*
