+#  through Clang's static analyzer and prepare the output to be uploaded
+#  back to the buildmaster. You might find it useful too.

+# Install Clang (you already have it on Mac OS X, apt-get install clang
+#  on Ubuntu, etc),
+# or download checker at http://clang-analyzer.llvm.org/ and unpack it in
+#  /usr/local ... update CHECKERDIR as appropriate.
