+    (description "@code{colorout} is an R package that colorizes R output when
+running in terminal emulator.
+
+R STDOUT is parsed and numbers, negative numbers, dates in the standard
+format, strings, and R constants are identified and wrapped by special ANSI
+scape codes that are interpreted by terminal emulators as commands to colorize
+the output.  R STDERR is also parsed to identify the expressions warning and
+error and their translations to many languages.  If these expressions are
+found, the output is colorized accordingly; otherwise, it is colorized as
+STDERROR (blue, by default).
+
+You can customize the colors according to your taste, guided by the color
+table made by the command @code{show256Colors()}.  You can also set the colors
+to any arbitrary string.  In this case, it is up to you to set valid values.")
