* Many of the options possible to set in the ArgumentList are not actually used |
| 28 |
|
|
* by the ingest command since they are not part of its interface, hence those |
| 29 |
|
|
* unused options cannot be set by the shell script. Of course if there is the |
| 30 |
|
|
* necessitty those parameters can be added and managed. |
| 31 |
|
|
* At the moment this approach worked fine and didn't add much complexity, |
| 32 |
|
|
* however if yet another command will need to use a similar approach it would |
| 33 |
|
|
* be good to consider creating different options handler for each command. |
