description             Test-case reduction for C compiler bugs
long_description        C-Reduce is a tool that takes a large C, C++, \
                        or OpenCL file that has a property of interest \
                        (such as triggering a compiler bug) and \
                        automatically produces a much smaller C/C++ \
                        file that has the same property. It is \
                        intended for use by people who discover and \
                        report bugs in compilers and other tools that \
                        process source code.
