     - will also need to compile in case you are on a

   - as you will see the command you are indicating is" --RuntimeDependencies"

   - you have called the Helper, through that you decide what 
   - to do and what not to do.

 * Commands

      - It installs the necessary dependencies to run a Zenda script 
      - without problems, it may or may not be necessary but it is 
      - recommended that it be installed to avoid future problems at runtime.

   => --BuildDependencies
      - Install all the necessary dependencies to be able to build the source 
      - code of Zenda and thus build a new executable, this can be useful
      - if you want to implement new functionalities to the technology, either
