# This is a script used by some Buildbot buildslaves to push the project
# 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.
