# 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.
