 %description
-Fast, correct, consistent, portable and convenient character string/text
-processing in every locale and any native encoding. Owing to the use of the
-'ICU' (International Components for Unicode) library, the package provides 'R'
-users with platform-independent functions known to 'Java', 'Perl', 'Python',
-'PHP' and 'Ruby' programmers. Available features include: pattern searching
-(e.g., with 'Java'-like regular expressions or the 'Unicode' collation
-algorithm), random string generation, case mapping, string transliteration,
-concatenation, Unicode normalization, date-time formatting and parsing and many
-more.
+A multitude of character string/text/natural language processing tools: pattern
+searching (e.g., with 'Java'-like regular expressions or the 'Unicode'
+collation algorithm), random string generation, case mapping, string
+transliteration, concatenation, sorting, padding, wrapping, Unicode
+normalisation, date-time formatting and parsing, and many more. They are fast,
+consistent, convenient, and - owing to the use of the 'ICU' (International
+Components for Unicode) library - portable across all locales and platforms.
