-\section{MAC OSX and BSD platform changes}
-Since we have no other information we are adding the [[MACOSXplatform]] variable
-to the list everywhere we find [[LINUXplatform]]. This may not be correct but
-we have no way to know yet. We have also added the [[BSDplatform]] variable.
-MAC OSX is some variant of BSD. These should probably be merged but we
-cannot yet prove that.
