for a description of Autoconf. You should write either @file{configure}
or @file{configure.ac}, but not both. The first line of
@file{configure.ac} should invoke the @code{m4} macro
pattern, you may be better off using a tool such as Flex to generate a
lexical scanner, or Bison to generate a parser, rather than using
@code{scanf}. For more information about these tools, see @ref{Top, , ,
