-/*
- * upb - a minimalist implementation of protocol buffers.
- *
- * Copyright (c) 2009 Joshua Haberman.  See LICENSE for details.
-
- * Defines a delimited (as opposed to null-terminated) string type and some
- * library functions for manipulating them.
- *
- * There are two primary reasons upb uses delimited strings.  One is that they
- * can be more efficient for some operations because they do not have to scan
- * the string to find its length.  For example, streql can start by just
- * comparing the lengths (very efficient) and scan the strings themselves only
- * if the lengths are equal.
- *
- * More importantly, using delimited strings makes it possible for strings to
- * reference substrings of other strings.  For example, if I am parsing a
- * protobuf I can create a string that references the original protobuf's
- * string data.  With NULL-termination I would be forced to write a NULL
- * into the middle of the protobuf's data, which is less than ideal and in
- * some cases not practical or possible.
