             Summary: Add ScriptFileDeployment Class
                 Key: LIBCLOUD-311
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-311
             Project: Libcloud
          Issue Type: Improvement
          Components: Compute
    Affects Versions: 0.12.3
            Reporter: Rudolf J Streif
            Priority: Minor


The ScriptDeployment class easily lets you deploy and execute a series of commands provided as a string with the script parameter. That works fine if you only have a few commands.

Sometimes it would be useful to write a script file and then execute it on a node. For that reason I am proposing the following patch:
