  ///
  /// \param Program Path of the program to be executed
  /// \param args A vector of strings that are passed to the program. The first
  /// element should be the name of the program. The list *must* be terminated by
  /// a null char * entry.
  /// \param env An optional vector of strings to use for the program's
  /// environment. If not provided, the current program's environment will be
  /// used.
  ///
  /// \returns Typically, this function will not return, as the current process
  /// will no longer exist, or it will call exit() if the program was successfully
  /// executed. In the event of an error, this function will return a negative
  /// value indicating a failure to execute.
