+#14 (@url{http://www.unicode.org/reports/tr14/}) line breaking algorithm.  It
+provides a fast and convenient way to determine line breaking opportunities in
+text.
+
+Note that this algorithm does not support break opportunities that require
+morphological analysis.  In order to handle such cases, please consult a system
+that provides this kind of capability, such as a hyphenation algorithm.
+
+Also note that this system is completely unaware of layouting decisions.  Any
+kind of layouting decisions, such as which breaks to pick, how to space
+between words, how to handle bidirectionality, and what to do in emergency
+situations when there are no breaks on an overfull line are left up to the
+user.")
