%    It seems that these files, although meant for compatibility with
%    \file{plain.tex} are also used as packages in \LaTeXe. The
%    disadvantage of that is that a number of compatibility measures
%    with other packages that are part of \file{babel.sty} are not
%    present. Therefore we issue an error and then load
%    \file{babel.def} to let the user continue processing his
%    document (at his own risk). 
%
%    First we determine whether we are loaded from \LaTeX\ by checking
%    whether |\PackageError| is defined.
%    \begin{macrocode}
\ifx\PackageError\undefined
%    \end{macrocode}
%    In this case we are not being loaded by \LaTeXe, so just define
%    |\ProvidesLanguage| to prevent an error when the \file{.ldf} file
%    is loaded.
%    \begin{macrocode}
  \def\ProvidesLanguage#1[#2 #3 #4]{%
    \wlog{Language: #1 #4 #3 <#2>}}%
\else
%    \end{macrocode}
%    Now we define an error message which `deletes' itself from
%    memory.
%    \begin{macrocode}
  \def\bblstyerror{%
    \PackageError{babel}%
      {You have used an old interface to call babel\MessageBreak
        You may expect compatibility problems wit other packages}%
      {You could proceed but don't complain if you run into errors}%
    \let\bblstyerror\@undefined
    }
%    \end{macrocode}
%    Now we can issue the error, it should appear when these files are
%    loaded from \LaTeXe, with \emph{or} without \file{hyphen.cfg}
%    preloaded in the format. 
% \changes{bbcompat-1.2e}{1999/04/20}{Added a check for
%    \cs{ProvidesLanguage}} 
%    \begin{macrocode}
  \ifx\ProvidesLanguage\undefined
%    \end{macrocode}
%    In this case \file{hyphen.cfg} wasn't loaded in the \LaTeXe\
%    format so we also need to provide a suitable definition for
%    |\ProvidesLanguage|.
%    \begin{macrocode}
    \bblstyerror
    \def\ProvidesLanguage{%
      \chardef\atcatcode=\catcode`\@
      \catcode`\@=11\relax
      \input babel.def\relax
      \catcode`\@=\atcatcode \let\atcatcode\relax
      \ProvidesLanguage}
%    \end{macrocode}
%    When we end up here, \file{hyphen.cfg} was loaded into the
%    format; we only need to issue the error from \LaTeXe.
%    \begin{macrocode}
  \else
    \bblstyerror
