+      Splint is a tool for statically checking C programs for security
+      vulnerabilities and coding mistakes.  With minimal effort, Splint
+      can be used as a better lint.  If additional effort is invested
+      adding annotations to programs, Splint can perform stronger
+      checking than can be done by any standard lint.
