%  The first set of definitions is what will be in effect outside of cyrillic,
%  i.e., in transliterated text.

%  Definition of \cydot is not ideal; real dot should be in an accent font.
\def\cydot{{\mathsurround=0pt$\cdot$}}

%  \ubar is the definition of \b from PLAIN; it may not work in math mode.
\def\ubar#1{\oalign{#1\crcr\hidewidth
    \vbox to.2ex{\hbox{\char22}\vss}\hidewidth}}

%  Soft and hard signs are represented in transliteration by prime and
%  double prime respectively.
\def\cprime{\/{\mathsurround=0pt$'$}}
\def\Cprime{{\mathsurround=0pt$'$}}
\def\cdprime{\/{\mathsurround=0pt$''$}}
\def\Cdprime{{\mathsurround=0pt$\ubar{\hbox{$''$}}$}}

\def\dbar{dj}           % make real barred d when accent font available
\def\Dbar{Dj}           %  ""

%  It would be nice to make these control sequences unnecessary; that will
%  probably require d to become active.

%  Stress marks are sometimes used in cyrillic text, mainly for pedagogic
%  reasons.  These definitions support stress marks within {\cyr ...};
%  in transliteration, they are suppressed.  Stress is indicated in
%  input by \! preceding a letter on which a stress mark is to appear;
%  an acute accent will appear in the output.  Since \! is also a plain
%  command, for negative thin space in math mode, test for math mode and
%  include the plain definition as appropriate.
