The XEPERSIAN-HM package
------------------------

In some cursive scripts such as Persian or Arabic, kashida is used to create
justification. In this type of justification characters are elongated rather
than expanding spaces between words.

The kashida justification in 'xepersian' has many bugs. Also it has problems
with some fonts such as 'HM Series' available at
'https://dma8hm1334.bitbucket.io' and 'X Series 2' available at
'http://wiki.irmug.com/index.php/X_Series_2'.

This package fixes the known bugs in 'xepersian' which uses the xetex engine.

The files 'xepersian-hm-*.tex' in the directory
'texmf-dist/doc/xelatex/xepersian-hm/' can be used as simple examples of
the usage of the package.

Please use the Bitbucket issue tracker:
'https://bitbucket.org/dma8hm1334/xepersian-hm/issues' to report a bug, request
a feature or if you have a comment.

I will do my best to fix all the bugs you report, but, unfortunately, time is a
big hurdle to overcome; so, my apologies in advance for those which I cannot
make time to fix.

% \section{Acknowledgments}
% In the first place I have to thank Donald Knuth for inventing TeX.
% During the development of this package I refered to  Stack Exchange network of
% question-and-answer (Q\&A) websites to solve problems for which I am grateful.
% I also would like to thank the developer teams of TeX's friends especially LaTeX, LuaTeX and XeTeX teams.

% \def\SubSecItem#1{\subsubsection*{\hskip 2em\large #1}\addcontentsline{toc}{subsection}{[#1]}}
% \newenvironment{Itemize}{\begin{itemize}[leftmargin=4em]}{\end{itemize}}
% 
% \SubSecItem{2020-03-17~v0.1}
% \begin{Itemize}
%   \item First standalone version.
% \end{Itemize}
% 
% \SubSecItem{2020-03-19~v0.2}
% \begin{Itemize}
%   \item Some minor changes.
% \end{Itemize}
% 
% \SubSecItem{2020-03-23~v0.3}
% \begin{Itemize}
%   \item Added documentation
% \end{Itemize}
% 
% \SubSecItem{2020-03-26~v0.4}
% \begin{Itemize}
%   \item Added DTX and INS files
% \end{Itemize}
% 
% \SubSecItem{2020-04-20~v0.5a}
% \begin{Itemize}
%   \item Added Kashida=glyph to the package options
%   \item Added \bslash discouragebadlinebreaks to prevent bad line breaks in a text (less than a paragragraph).
% \end{Itemize}
% 
% \SubSecItem{2020-04-26~v0.5b}
% \begin{Itemize}
%   \item If the kashida glyph is used to stretch the text, then the main font is checked for availability of the kashida character.
%   \item Two optional arguments added in \bslash discouragebadlinebreaks macro.
% \end{Itemize}
% 
% \SubSecItem{2020-05-01~v0.5c}
% \begin{Itemize}
%   \item The documentation is divided into two parts: User documentation and Source code documentation.
%   \item The example file is divided into two parts: An example for the option Kashida=glyph and the other one for Kashida=hrule.
% \end{Itemize}
% 
% \SubSecItem{2020-05-07~v0.5d}
% \begin{Itemize}
%   \item Added a new section to the user documentation titled: Brief outline of the issues.
%   \item An error is trigerred if the value of Kashida option is not specified.
% \end{Itemize}
% 
% \SubSecItem{2020-05-12~v0.5e}
% \begin{Itemize}
%   \item Disturbance of ligatures caused by activation of kashida is fixed.
% \end{Itemize}
% 
% \SubSecItem{2020-05-20~v0.5f}
% \begin{Itemize}
%   \item Reduced the length of items created by zref package in \bslash jobname.aux file.
%   \item If the option Kashida=glyph is used, a warning message is added to the log file
%     which emphasizes that the option is experimental.
% \end{Itemize}
% 
% \SubSecItem{2020-05-31~v1.0a}
% \begin{Itemize}
%   \item The option 'Kashida=hrule' is changed to 'Kashida=leaders+hrule'.
%   \item The option 'Kashida=leaders+glyph' is added. Since with this option kashida glyph
%     leaders are used to stretch the text, nothing is saved in .aux files.
% \end{Itemize}
% 
% \SubSecItem{2020-06-04~v1.0b}
% \begin{Itemize}
%   \item Added two options Kashida=On and Kashida=Off.
% \end{Itemize}
% 
% \SubSecItem{2020-07-20~v1.0c}
% \begin{Itemize}
%   \item Fixed the problem with the option ligatures=default.

% \SubSecItem{2020-08-05~v1.0d}
% \begin{Itemize}
%   \item In the new version of LaTeX3, the name of some of the XeTeX control sequences has changed.
%     These changes are applied in this version of xepersion-hm.
% \end{Itemize}
% 
% \SubSecItem{2020-09-04~v1.1a}
% \begin{Itemize}
%   \item Added the color option.
%   \item Added a few sections to the User Documentation.
%   \item Split the file containing kashida code.
