Need a refresher on creating application icons (in OSX).
As I remember, the procedure in OS9 went something like this:
1 - create a resource file for the application.
2 - In the resource file, create the following resources:
        BNDL, FREF, ic14, ic18, ICN#, ics#, ics4 and ics8.
3 - in the BNDL resource, define a TYPE that will be associated
    with the file that the application will create. For that
    TYPE, complete the icon drawings that will appear in the
    ic and ics.
4 - What should the BNDL Signature be set to ??
5 - In OS 9, it might have been necessary to rebuild the desktop.
    How is this done in OSX.
6 - I vaguely remember that a checkbox had to be checked
    relating to 'has a bndl'.

Can someone fill in the missing steps and correct any errors.

TIA
