+ (description
+ "This package provides the @code{ShortText} type which is suitable for
+keeping many short strings in memory. This is similiar to how
+@code{ShortByteString} relates to @code{ByteString}. The main difference
+between @code{Text} and @code{ShortText} is that @code{ShortText} uses UTF-8
+instead of UTF-16 internally and also doesn't support zero-copy
+slicing (thereby saving 2 words). Consequently, the memory footprint of
+a (boxed) @code{ShortText} value is 4 words (2 words when unboxed) plus the
+length of the UTF-8 encoded payload.")
