% \section{Introduction}
%
%    This file contains alternate font definition statements for the
%    fonts \fn{cmmib} and \fn{cmbsy} that are tailored to the set of
%    sizes provided in the Y\&Y/Blue Sky Research PostScript versions of
%    the AMSFonts collection. In that font set, the only \fn{.tfm} files
%    provided below size 10 are 5 and 7, rather than 5,6,7,8,9. This
%    means that if the standard \fn{.fd} files are used, any attempt to
%    use 6,8,9 point math will result in error messages about missing
%    \fn{.tfm} files.
%
%    Rather than provide substitute versions of the standard
%    \fn{OMLcmm.fd} and \fn{OMScmsy.fd} font definition files, we put
%    the alternate font definitions in package form so that any document
%    that uses them will have an explicit indication in the document:
% \begin{verbatim}
% \usepackage{cmmib57}
% \end{verbatim}
%    Scaling from sizes 5 and 7 to the surrounding sizes results in
%    some font metric differences, so the line breaks (and,
%    consequently, page breaks) resulting from that alternative won't
%    necessarily be the same as with the standard \LaTeX{} font
%    definition files.
