          <para>Helps to create a <filename>configure.in</filename> file for a

          for a software package; it prints the identifiers that the package
          uses in C preprocessor conditionals. If a package has already been set
          up to have some portability, this program can help determine what
          <command>configure</command> needs to check for. It can also fill in
          gaps in a <filename>configure.in</filename> file generated by
