Runs through a series of dialogs to end up with a build plan for Tcl.  Then executes the plan.

N.B. You cannot run this script from the Script Editor application.  You must run it from the Finder.

The options are:
 • What To Build: Shells, Libraries or Both
 • Architecture: PowerPC, 68k or Both
 • Shared or Static or Both
    Note - we do not currently build CFM68K apps, so Shared only applies to PowerPC
 • Fat or Non-Fat
    Note - Currently, the Fat version of Tcl is a PowerPC shared version, so you won't get this
                option unless you choose Shared.  You also have to build the 68K non-fat shell to do this.
