+------------------
+
+To customize compiler, set ``CXX`` environment variable to point to compiler binary and, in
+some case, specify type of the compiler using ``--check-cxx-compiler``.  For example, when
+using clang compiler on Linux system, use the following:
+
+::
+
+    CXX=clang++ ./waf configure --check-cxx-compiler=clang++
