Usage: $0 [-a|--artifact ARTIFACT] [-g|--host GIT_HOST] [REPO] [REF]
|
|
Get the hash of a package.
|
|
|
|
REPO must be in the form of OWNER/REPO, and REF must be a commit sha, branch, or tag.
|
|
|
|
Options:
|
|
-g, --host <GIT_HOST> What Git host to use (defaults to github.com)
|
|
|
|
-a, --artifact <ARTIFACT> The artifact to download (implies -t)
|
|
If -t is specified but not -a, fetches a tag archive.
