# Build the .deb by hand: stage the release binaries + resources, compute
# the FULL runtime dependency set with dpkg-shlibdeps (Debian-family names
# of the build distro), and pack with dpkg-deb. Run from the repo root
# after `cargo build --release`.
#
# Usage: tooling/package/build-deb.sh <version> [<variant>]
#   <variant> marks the build distro in the package version and file name:
#   CD passes "debian" for the general build and "openkylin" for the
#   openKylin builds. The "+" suffix is valid Debian version syntax and
#   sorts above the plain version.
