12 | * Some command-line parameters need to be saved up until after |
13 | * we've loaded the saved session which will form the basis of our |
14 | * eventual running configuration. For this we use the macro |
15 | * SAVEABLE, which notices if the `need_save' parameter is set and |
16 | * saves the parameter and value on a list. |
17 | * |
18 | * We also assign priorities to saved parameters, just to slightly |
19 | * ameliorate silly ordering problems. For example, if you specify |
20 | * a saved session to load, it will be loaded _before_ all your |
21 | * local modifications such as -L are evaluated; and if you specify |
22 | * a protocol and a port, the protocol is set up first so that the |
23 | * port can override its choice of port number. |

26 | * processing of further command-line options depends on whether or |
27 | * not the loaded session contained a hostname. So it must be |
28 | * executed immediately.) |
