 The example above illustrates a situation where an app package (`app.tar.gz`) will be deployed to 2 remote hosts (`remote1` and `remote2`). An md5 checksum will be deployed as well. After deploying, the md5 checksum is used to check the deployed package. If successful the package is extracted.

 ## Important
 The script passed to **script** will be executed on remote machines directly after rsync completes to deploy the files. It will be executed step by step until a command returns a non-zero exit-code. If this happens, the entire plugin will exit and fail the build.
