longDescription = ''
C-Reduce is a tool that takes a large C or C++ program that has a
property of interest (such as triggering a compiler bug) and
automatically produces a much smaller C/C++ program that has the same
property. It is intended for use by people who discover and report
bugs in compilers and other tools that process C/C++ code.
