Early exit techniques

[pjaquiery]

At present I do store information in a temporary macro prior to the throw. However this whole technique requires an explicit throw.

In many of my build projects I check for various macros passed as command line parameters and use those to generate reports and such. I those cases I generally don't want the full build so I exit early using an uncaught throw.

What I'd like would be an Exit step that simply terminates the build at that point.

In other places I test the result of a build step (compile for example) and Abort the build if the compile failed. In that case I'd like to get fail processing performed and set a temporary variable (to indicate what failed). At present I use a small chunk of JScript to get this done.

All of this can be done in some fashion at present; just not in an obvious and clean fashion. An Exit/Abort build step would make the flow of control obvious rather than hidden.
