* A map of all the options the parser recognises. |

|
* The map is actually an array which associates short or long options with |
|
12
|
|
|
* their appropriate parameters. Options which have both long and short |
|
13
|
|
|
* versions would be repeated. This structure is used to quickly find the |
|
14
|
|
|
* paramters of an option whether in the short form or long form. This |
|
15
|
|
|
* parameter is automatically populated by the library as options are added. |
