+/**
+ * @file
+ *
+ * This file looks and acts like /usr/include/ftw.h, with one
+ * <em>significant</em> difference.  The standard ftw() and nftw()
+ * functions do not permit passing an arbitrary pointer into the
+ * callback.  This greatly limits the functions' usefulness on
+ * object-oriented systems and in thread-safe libraries.  Thus the
+ * header file declares two new functions, new_ftw() and new_nftw(),
+ * that act the same as the original, with the addition of an
+ * arbitrary void pointer as the last argument.  This void pointer,
+ * which may be NULL, is passed into the callback function's last
+ * parameter.
