+    "This library provides functions for manipulating Unicode strings and for
+manipulating C strings according to the Unicode standard.
+
+GNU libunistring is for you if your application involves non-trivial text
+processing, such as upper/lower case conversions, line breaking, operations
+on words, or more advanced analysis of text.  Text provided by the user can,
+in general, contain characters of all kinds of scripts.  The text processing
+functions provided by this library handle all scripts and all languages.
+
+libunistring is for you if your application already uses the ISO C / POSIX
+<ctype.h>, <wctype.h> functions and the text it operates on is provided by
+the user and can be in any language.
+
+libunistring is also for you if your application uses Unicode strings as
+internal in-memory representation.")
