+// This header is an extension.  It defines two streambufs:
+// stdio_istreambuf, a read-only streambuf synchronized with a C stdio
+// FILE object, and stdio_ostreambuf, a write-only streambuf
+// synchronized with a C stdio FILE object.  Note that neither
+// stdio_istreambuf nor stdio_ostreambuf is a template; both classes
+// are derived from basic_streambuf<char, char_traits<char> >.
+
+// Note: the imbue() member function is a no-op.  In particular, these
+// classes assume that codecvt<char, char, mbstate_t> is always an identity
+// transformation.  This is true of the default locale, and of all locales
+// defined for the C I/O library.  If you need to use a locale where
+// the codecvt<char, char, mbstate_t> facet performs a nontrivial
+// conversion, then you should use basic_filebuf<> instead of stdio_istreambuf
+// or stdio_ostreambuf.  (If you don't understand what any of this means,
+// then it's not a feature you need to worry about.  Locales where
+// codecvt<char, char, mbstate_t> does something nontrivial are a rare
+// corner case.)
