+  <p>Invoking the BoostCon tool:</p>
+  <pre>
+$ clang -cc1 -boostcon t.cpp
+</pre>
+
+  <p>Teach the BoostCon action to identify and print C++ classes:</p>
+  <pre>
+bool VisitCXXRecordDecl(CXXRecordDecl *D) {
+  std::cout << D->getNameAsString() 
+    << '\n';
+  return false;
+}
+</pre>
+
+  <p>Walk and print base classes of a class:</p>
+  <pre>
+for(CXXRecordDecl::base_class_iterator 
+      B = D->bases_begin(), BEnd = D->bases_end();
+      B != BEnd; ++B) {
+  QualType BaseType = B->getType();
+  std::cout << "  " << BaseType.getAsString() 
+    << '\n';
+}
+</pre>
+
+  <p>Retrieve the C++ class declaration from a base type:</p>
+  <pre>
+if (const RecordType *RTy
+             = BaseType->getAs<RecordType>()) { 
+  RecordDecl *Base = RTy->getDecl();
+  if (CXXRecordDecl *BaseCXX
+        = dyn_cast<CXXRecordDecl>(Base)) {
+  
+  }
+}
