The wiki has a small into, perfectable but nice
enough while the doc here has no such thing.
So, copy the intro from the wiki into the entrypoint
of the documentation (and convert the wikimedia markup
into restructuredtext).

+About Sparse
+------------
+
+Sparse, the semantic parser, 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 `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
+function acquires or releases.
+
+Linus Torvalds started writing Sparse in 2003, initially targeting issues such
+as mixing pointers to user address space and pointers to kernel address space.
+
+Josh Triplett was Sparse's first maintainer in 2006. This role was taken over
+by Christopher Li in 2009 and by Luc Van Oostenryck in late 2018.
