+/* To use this file with libraries the following macro is useful:
+
+     #define _ESTREAM_EXT_SYM_PREFIX _foo_
+   
+       This prefixes all external symbols with "_foo_".
+
+   For the implementation of the code (estream-printf.c) the following
+   macros may be used to tune the implementation for certain systems:
+
+     #define _ESTREAM_PRINTF_MALLOC foo_malloc
+     #define _ESTREAM_PRINTF_FREE   foo_free
+
+       Make estream_asprintf and estream_vasprintf use foo_malloc and
+       foo_free instead of the standard malloc and free functions to
+       allocate the memory returned to the caller.
+
+     #define  _ESTREAM_PRINTF_EXTRA_INCLUDE "foo.h"
+
+       This includes the file "foo.h" which may provide prototypes for
+       the custom memory allocation functions.
