+= Mac OS X =
+
+On Mac OS X you can create a universal library, a library that works
+on multiple systems. You can do this by specifying multiple `-arch`
+options to the compiler (but not to the preprocessor):
+
+ #> ./configure CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                CXXCPP="g++ -E" --disable-dependency-tracking
+
+This will produce a universal yat library with 4 architectures. If
+your OS X does not support both Power-PC and Intel-based processors,
+you can omit these architectures. Also, required libraries, GSL and
+CBLAS, need to be available as universal libraries with desired
+architectures.
