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)
   -t             full analysis on {pointer} build option (default: $TRACEPTR)
