+description A version of Apple's libunwind library that is included in libSystem
+long_description Apple's libunwind library (part of libSystem) was \
+ released as OSS and is now stewarded by the LLVM \
+ Project. This version installs outside of the normal \
+ filesystem hierarchy in order to not accidentally \
+ conflict with the host implementation that other ports \
+ may expect.
