-These single-binary pre/postinstall scripts are the ones currently used by the supplied PackageMaker projects (OS X 10.4.pmdoc and OS X 10.5+.pmdoc).

-Pre/postupgrade are hard links to their respective install version since the pre/postinstall scripts handle both fresh install and upgrade cases. Be careful when editing pre/postinstall that the hard links still work; many editors (including Xcode) break the hard link when editing a file, meaning you'd need to delete pre/postupgrade and recreate the links as follows:
-
-ln preinstall preupgrade
-ln postinstall postupgrade

+These single-binary pre/postinstall scripts are the ones currently used by the supplied PackageMaker projects, and handle both fresh and upgrade installations. The pre/postupgrade scripts must be exact duplicates of (or soft links to) the ~install scripts, and are supplied only for OS X 10.4 where upgrade installation would fail without them; for OS X 10.5 and upwards Apple's Installer no longer uses them.
