If the package needs to install GNU info
      files, list them in INFO (without the
      trailing .info), one entry per document.
      These files are assumed to be installed to
      PREFIX/INFO_PATH.  Change
      INFO_PATH if the package uses a different
      location.  However, this is not recommended.  These entries
      contain just the path relative to
      PREFIX/INFO_PATH.  For example,
      lang/gcc34 installs info files to
      PREFIX/INFO_PATH/gcc34, and
      INFO will be something like this:
INFO= gcc34/cpp gcc34/cppinternals gcc34/g77 ...
Appropriate installation/de-installation code will be
      automatically added to the temporary
      pkg-plist before package
      registration.
