% Russian-style hyphenation of inline equations
% (C) 2009-2010 Denis Ryabov.
%
% Based on ideas and code from M.I.Grinchuk "TeX and Russian
%                 Traditions of Typesetting", TUGboat 17 (1996) 4.
%
% CHANGELOG:
% -------------------- 0.98 [31-January-2010] --------------------
% [+] hyphenation on :=
% [+] correct work with 'icomma' package and option 'icomma' of
%     'eulervm' package
% [+] correct work with 'program' package
% [+] symbols have been added from  boisik, euler, fourier,
%     lucbmath, lucidabr, lucmin, lucmtime, luctime, mathbbol,
%     mdwmath, sbbm, stmaryrd and wasysym packages.
% [-] remove shrinking of space in math (breaked url package)
% [#] don't hyphenate after punctuation (',', ';', '\colon' etc.)
% [#] create broken commands as robust
% [#] some fixes of redeclaring of AMS commands
% [#] commented hyphenation on \ldots � \cdots, as TeX doesn't
%     here by default
% -------------------- 0.97 [08-October-2009] --------------------
% [#] problem with operators like '+^\leq'
% -------------------- 0.96 [29-September-2009] ------------------
% [#] problem with '-' in AMS \DeclareMathOperator
% [#] problem with \ldots in text mode
% -------------------- 0.95 [28-September-2009] ------------------
% [#] problem with sub/sup-scripts after relations
% [+] hyphenation on \ldots
% [+] AMS/Lucida left brackets (lvert, lVert, ulcorner, llcorner)
%     support
% [+] mathbbol.sty left bracket (Lbrack) support
% [^] huge code refactoring
% -------------------- 0.91 [21-September-2009] ------------------
% [#] problem with space after brackets
% -------------------- 0.90 [20-September-2009] ------------------
% [!] first public release
%
%
% KNOWN ISSUES:
% expressions like $\sum -y$ require manual insertion of \nobr
% before - (that is $\sum \nobr-y$)
% 'xy' package: should be loaded after 'rumathbr' to work properly
% 'breqn' package: cannot work together with 'rumathbr'
