description             A portable way to unwind the call-chain of a program
long_description        Apple's implementation of the libunwind library \
                        provides a source compatible implementation of the \
                        http://www.nongnu.org/libunwind/man/libunwind(3).html \
                        API to unwind a call-chain. Headers only, because the \
                        library is included in the base operating system.
