+@chapter Character Type Macros and Functions (@file{ctype.h})
+This chapter groups macros (which are also available as subroutines)
+to classify characters into several categories (alphabetic,
+numeric, control characters, whitespace, and so on), or to perform
+simple character mappings.
+
+The header file @file{ctype.h} defines the macros.
