Usage: $ME [OPTIONS] ACTION

OPTIONS:
   -h             print this help message
   -p profile     aws profile name
   -a arch        set build arch (default: $GOARCH)
   -o os          set build OS (default: $GOOS, windows is supported)
   -b bucket      set the upload bucket name (default: $BUCKET)
   -f folder      set the upload folder name in the bucket (default: $FOLDER)
   -r             enable -race build option (default: $RACE)

ACTION:
   build       build binaries only (default action)
   upload      upload binaries to s3
   pubwallet   upload wallet to public bucket (bucket: $PUBBUCKET)

   harmony|txgen|bootnode|wallet|beacon
               only build the specified binary

EXAMPLES:

# build linux binaries only by default
