\ProvidesFile{cp1251-light.def}
[2005/12/24 v1.2 Light input encoding file]
%
% \changes{v1.0}{2004/09/23}{This version was uploaded to CTAN}
% \changes{v1.1}{2005/01/09}{Replace \textrm{\normalfont...} to \textnormal}
% \changes{v1.1}{2005/01/09}{More comprehensive test of font encoding}
% \changes{v1.2}{2005/12/24}{Test the \cyrillicencoding to be \undefined}
%
% Using of cyrillic input encodings has two major disadvantages:
%
% * cyrillic letters are forbidden in names of labels because
% they are active and
% * cyrillic letters disappear in math mode because they do not
% belong to ordinary math fonts.
%
% The light version of the CP1251 input encoding partially removes both
% these disadvantages: it declares common cyrillic letters in the range
% of \CYRA--\cyrya as `other' symbols (with catcode 12), activates them in
% math mode only (with mathcode "8000), and typesets common cyrillic letters
% in math mode with the default text font. All these actions are applied
% if the output cyrillic encoding is one of T2A, T2B, T2C, or X2 for
% which the input and output codes of common cyrillic letters coinside.
% Otherwise, the cp1251-light works as cp1251.
