% LaTeX2e package for typesetting Devanagari script with the:
%
%  `devnag'  pre-processor and  dvng  fonts
%       by Frans J. Velthuis' <velthuis@rc.rug.nl>
%
%   and the  dev.sty  LaTeX-2e interface 
%       by Dominik Wujastyk <D.Wujastyk@ucl.ac.uk>
%
%   retaining support for the old  dev2e.sty  LaTeX-2e interface 
%       by Dominik Wujastyk <D.Wujastyk@ucl.ac.uk>
%
% Furthermore it can be used with the transcription scheme
% devised by Jeroen Hellingman, for his  `patc' pre-processor
% requiring macro files:  dnmacs.tex  and  dntrmacs.tex
%
%
% These resources are *not* included with this package.
% Obtain them from CTAN:  http//ctan.tug.org/ctan
%
% ===================================================================
% This package has a corresponding implementation for  LaTeX2HTML 
% called:  devnagri.perl .
% With LaTeX2HTML the options on the \usepackage line specify which
% pre-processor and transcription mode to use.
%
% Usage:
%
%  \usepackage[devnag]{devnagri}     %|  uses Velthuis' pre-processor
%  \usepackage[hindi]{devnagri}      %|    patc -p <option>.pat
%  \usepackage[marathi]{devnagri}    %|  with language options, and macros:
%  \usepackage[nepali]{devnagri}     %|   dngmacs.tex  dntrmacs.tex
%  \usepackage[sanskrit]{devnagri}   %|  
%
%  \usepackage{devnagri}             %|  source already pre-processed
%  \usepackage[preprocess]{devnagri} %|  same as  \usepackage[devnag]{devnagri}
%
%  \usepackage[dev209]{devnagri}       %|  old LaTeX-209 version
%  \usepackage[olddevnag]{devnagri}    %|  old LaTeX-209 version
%  \usepackage[old,...]{devnagri}      %|  uses LaTeX-209 version with others
%
%  \usepackage[patc]{devnagri}         %|  also uses Jeroen Hellingman's 
%  \usepackage[patc,hindi]{devnagri}   %|    patc -p <option>.pat
%  \usepackage[patc,marathi]{devnagri} %|  with language options, and macros:
%  \usepackage[patc,nepali]{devnagri}  %|   dngmacs.tex  dntrmacs.tex
%  \usepackage[patc,sanskrit]{devnagri}%|
