+ (description
+ "Flex is a tool for generating scanners. A scanner, sometimes
+called a tokenizer, is a program which recognizes lexical patterns in
+text. The flex program reads user-specified input files, or its standard
+input if no file names are given, for a description of a scanner to
+generate. The description is in the form of pairs of regular expressions
+and C code, called rules. Flex generates a C source file named,
+\"lex.yy.c\", which defines the function yylex(). The file \"lex.yy.c\"
+can be compiled and linked to produce an executable. When the executable
+is run, it analyzes its input for occurrences of text matching the
+regular expressions for each rule. Whenever it finds a match, it
+executes the corresponding C code.")
