    --prefix=PREFIX                 install files in tree rooted at PREFIX

    --enable-coverage               enable build with code coverage support
    --enable-libc++                 using libc++ instead of libstdc++, only valid for clang compiler

Dependencies:
    c/c++ compiler
    GNU make
    cmake           http://www.cmake.org/
    protobuf        https://code.google.com/p/protobuf/
    kerberos        http://web.mit.edu/kerberos/
    libgsasl        http://www.gnu.org/software/gsasl/
    libxml2         http://xmlsoft.org/
    boost 1.53+     http://www.boost.org/
                    [boost is not required if c++ compiler is g++ 4.6.0+ or clang++ with stdc++]

Example:
    mkdir build
    cd build
    ../bootstrap --prefix=/path/to/install --dependency=/path/to/protobuf:/path/to/kerberos/:path/to/others
    make
    make install
