 BUILDING
 --------
 
+	./bootstrap (skip if using tarball)
+	./configure
 	make
-	#force 32-bit build with: make -f Makefile32
-	#force 64-bit build with: make -f Makefile64
 	make install
-	
+
+	Hints:	Forcing 32-bit build:
+		* CFLAGS=-m32 ./configure
+
+		Forcing 64-bit build:
+		* CFLAGS=-m64 ./configure
+
+		Forcing a 32-bit build with down to 386 compatibility:
+		* CFLAGS=-m32 ./configure --target=i386-pc-linux-gnu
+
+ARCHITECTURES SUPPORTED
+-----------------------
+
+Currently, x86 (i386, i486, i586, i686), x86 64, PowerPC 32/64 and S390 are
+supported. The current use of sys_futex() makes it Linux-dependent, although
+this portability limitation might go away in a near future by using the pthread
+cond vars.

 	DEBUG_YIELD is used to add random delays in the code for testing

+SMP support
+
+	By default the library is configured to use synchronization primitives
+	adequate for SMP systems. On uniprocessor systems, support for SMP
+	systems can be disabled with:
+
+		./configure --disable-smp-support
+
+	theoretically yielding slightly better performance.
