->This document is an informal description of the HAL capabilities and
-is not intended to be full documentation, although it may be used as a
-source for such. It also describes the HAL as it is currently
-implemented for the architectures targeted in this release. It most
-closely describes the HALs for the MIPS, I386 and PowerPC HALs. Other
-architectures are similar but may not be organized precisely as
-described here.</P
