+#  through Clang's static analyzer and prepare the output to be uploaded
+#  back to the buildmaster. You might find it useful too.
+
+# To use: get CMake from http://cmake.org/ or "apt-get install cmake" or whatever.
+# And download checker at http://clang-analyzer.llvm.org/ and unpack it in
+#  /usr/local ... update CHECKERDIR as appropriate.
+
+# this currently expects a mercurial working copy that it can modify a little.
