Usage: sync-to-aws-homebrew-tap -r <repo> -b <binary-basename> -p <platform_pairs>
33+
Syncs tar.gz\'d binaries to the aws/homebrew-tap
34+
35+
Example: sync-to-aws-homebrew-tap -r "aws/amazon-ec2-instance-selector"
36+
Required:
37+
-b Binary basename (i.e. -b "ec2-instance-selector")
38+
39+
Optional:
40+
-r Github repo to sync to in the form of "org/name" (i.e. -r "aws/amazon-ec2-instance-selector") [DEFAULT: output of \`make repo-full-name\`]
41+
-v VERSION: The application version of the docker image [DEFAULT: output of \`make version\`]
42+
-p Platform pair list (os/architecture) [DEFAULT: linux/amd64]
43+
-d Dry-Run will do all steps except pushing to git and opening the sync PR
