usage: $0 [--rebuild] [--local] [--dryrun]

$0 builds D2 release archives into ./ci/release/build/<version>/d2-<version>.tar.gz

The version is detected via git describe which will use the git tag for the current
commit if available.

Flags:

--rebuild: By default build.sh will avoid rebuilding finished assets if they
           already exist but if you changed something and need to force rebuild, use
           this flag.
--local:   By default build.sh uses \$TSTRUCT_MACOS_AMD64_BUILDER,
           \$TSTRUCT_MACOS_ARM64_BUILDER, \$TSTRUCT_LINUX_AMD64_BUILDER and
           \$TSTRUCT_LINUX_ARM64_BUILDER to build the release archives. It's required for
           now due to the following issue: https://github.com/terrastruct/d2/issues/31
           With --local, build.sh will cross compile locally.
           warning: This is only for testing purposes, do not use in production!
