16 /* OK, here's how this works. Each of the steps needed for install -
17 dialogs, downloads, installs - are in their own files and have some
18 "do_*" function (prototype in dialog.h) and a resource id (IDD_* or
19 IDD_S_* in resource.h) for that step. Each step is responsible for
20 selecting the next step! See the NEXT macro in dialog.h. Note
21 that the IDD_S_* ids are fake; those are for steps that don't
22 really have a controlling dialog (some have progress dialogs, but
23 those don't count, although they could). Replace the IDD_S_* with
24 IDD_* if you create a real dialog for those steps. */
