Specify the command Dakota uses to launch analysis driver(s) and filters

## Specification

Alias: none

Argument(s): none

Default: driver/filter invocation syntax augmented with file names

## Description

The typical commands that Dakota uses to launch analysis drivers are:

    > analysis_driver parameters_file_name results_file_name

Dakota will automatically arrange the executables and file names.

If the analysis driver requires a different syntax, the entire command can be specified as the analysis driver and the `verbatim` keyword will tell Dakota to use this as the command.

Note, this will not allow the use of `file_tag`, because the exact command must be specified.

For additional information on invocation syntax, see the Interfaces chapter of the Users Manual[4].

## Examples

In the following example, the analysis_driver command is run without any edits from Dakota.

    interface
      analysis_driver = "matlab -nodesktop -nojvm -r 'MatlabDriver_hardcoded_filenames; exit' "
        fork
          parameters_file 'params.in'
          results_file 'results.out'
          verbatim # this tells Dakota to fork the command exactly as written, instead of appending I/O filenames

The -r flag identifies the commands that will be run by matlab. The Matlab script has the parameters_file and results_file names hardcoded, so no additional arguments are required.
