<a name="line-29"></a> This module is intended to allow the launch of the same application
<a name="line-30"></a> but changing the parameters using the user response. For example, when
<a name="line-31"></a> you want to open a image in gimp program, you can open gimp and then use
<a name="line-32"></a> the File Menu to open the image or you can use this module to select
<a name="line-33"></a> the image in the command line.
<a name="line-34"></a>
<a name="line-35"></a> We use Prompt to get the user command line. This also allow to autoexpand
<a name="line-36"></a> the names of the files when we are writing the command line.
