DocFiles: DOCUMENTS
DescPackaging:  <<
	Borrowed liberally from Macports.
	
	Needs a gfortran; I've arbitrarily chosen gcc47 for now.

	Needs -ff2c when using Accelerate.framework, but not when using
	ATLAS.
<<
DescPort: <<
	Dynamic library originally courtesy of Ben Abbot.  I've tweaked it to
	have a nonzero compatibility_version and current_version.  Additional
	tweaks thanks to J-F Mertens and Peter O'Gorman
	
	Fortran files are built at -O0 to avoid runtime crashes--thanks to
	Martin Costabel for bringing this up.
