I was looking at the STP12.2.3.bld script that comes with the release,
and noticed that all the directory separators are for the Mac ($:), and
thus the block doesn't execute correctly.  Now, I can do a simple
search and replace, and that will fix it, but I was wondering:

A)  Is there already a better way to do this that just works, and if not
B)  Would it be worthwhile to try and generalize this so that non-Mac
folks
    don't have to monkey around with this every time?

Thanks!
