+implements the locale independent Unicode text segmentation algorithms to
+detect grapheme cluster, word and sentence boundaries and the Unicode line
+breaking algorithm to detect line break opportunities.
+
+The library is independent from any IO mechanism or Unicode text data
+structure and it can process text without a complete in-memory
+representation.")
