# A small shell script invoked from CI on the final Linux builder which actually
# assembles the release artifacts for a particular platform. This will take the
# binary artifacts of previous builders and create associated tarballs to
# publish to GitHub.
#
# The first argument of this is the "platform" name to put into the tarball, and
# the second argument is the name of the github actions platform which is where
# we source binaries from. The final third argument is ".exe" on Windows to
# handle executable extensions right.
#
# Usage: build-tarballs.sh PLATFORM [.exe]

# where PLATFORM is e.g. x86_64-linux, aarch64-linux, ...
