+The unit test DirectIO.java in this directory depend on a native library
+(libDirectIO). This native library is built off-line and the
+resulting libDirectIO.so or libDirectIO.dylib for each processor/OS 
+combination is checked into the workspace. The reason for this is because 
+the test environment may not have the required compilers/build environment.
+
+In order to rebuild libDirectIO the following is required :-
+
+1. Check-out each of the shared libraries (sccs edit)
+
+2. Edit DirectIO.c with the appropriate changes
+
+3. Execute the make script (gnumake all) on each processor/OS so
+that the appropriate lib/<platform>/libDirectIO.so or lib/<platform>/libDirectIO.dylib 
+is built.
+
+4. Test the changes
+
+5. Check-in each of the shared library (sccs delget)
+
+
+For step 4 (re-building libDirectIO) the following environment is required:
+
+(a) JAVA_HOME needs to be set to J2SE directory
+
+(b) For Solaris the SOS8 'cc' needs to be on the PATH, check using:
+	# cc -V
+	cc: Sun C 5.5 2003/03/12
+
+(c) Execute the make script :-
+        Solaris:        gmake
+        Linux:          gmake
+        MacOS:          make
