+It provides a compiler frontend capable of parsing most of ANSI C as well as
+many GCC extensions, and a collection of sample compiler backends, including a
+static analyzer also called @file{sparse}.  Sparse provides a set of
+annotations designed to convey semantic information about types, such as what
+address space pointers point to, or what locks a function acquires or
+releases.")
