(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 @file{lex.yy.c}, which defines the function
|
|
@code{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.")
