	\small\textsc{README:}
	The changes-package allows the user to manually markup changes of text, such as additions, deletions, or replacements.
	Changed text is shown in a different color; deleted text is striked out.
	The package allows free definition of additional authors and their associated color.
	It also allows you to change the markup of changes, authors, or annotations.

%^^A ---- usage
\section{Using the \chpackage{changes}-package}
\label{sec:usage}

In this section a typical use case of the \chpackage{changes}-package is described.
You can find the detailed description of the package options and new commands in \autoref{sec:user}.

We start with the text you want to change.
You want to markup the changes for each author individually.
Such a change markup is well-known in WYSIWYG text processors such as \emph{LibreOffice}, \emph{OpenOffice}, or \emph{Word}.

The \chpackage{changes}-package was developed in order to support such change markup.
The package provides commands for defining authors, and for marking text as added, deleted, or replaced.
In order to use the package, you have to follow these steps:

\begin{enumerate}
	\item use \chpackage{changes}-package
	\item define authors
	\item markup text changes
	\item typeset the document with \LaTeX
	\item output list of changes
	\item remove markup
\end{enumerate}


\minisec{use \chpackage{changes}-package}

In order to activate change management, use the \chpackage{changes}-package as follows:

\chcommand{usepackage\{changes\}}

respectively

\chcommand{usepackage[<options>]\{changes\}}

You can use the options for defining the layout of the change markup.
You can change the layout after using the \chpackage{changes}-package as well.

For detailed information please refer to \autoref{sec:user:options} and \autoref{sec:user:customizingoutput}.


\minisec{define authors}

The \chpackage{changes}-package provides a default anonymous author.
If you want to track your changes depending on the author, you have to define the needed authors as follows:

\chcommand{definechangesauthor[<options>]\{id\}}

Every author is uniquely identified through his or her id.
You can give every author an optional name and/or color.

For detailed information please refer to \autoref{sec:user:authormanagement}.


\minisec{markup text changes}

Now everything is set to markup the changed text.
Please use the following commands according to your change:

for newly added text:\\
\chcommand{added[id=<id>, remark=<remark>]\{text\}}

for deleted text:\\
\chcommand{deleted[id=<id>, remark=<remark>]\{text\}}

for replaced text:\\
\chcommand{replaced[id=<id>, remark=<remark>]\{text\}}

Stating the author's id and/or a remark is optional.

For detailed information please refer to \autoref{sec:user:changemanagement}.


\minisec{typeset the document with \LaTeX}

After marking your changes in the text you are able to display them in the generated document by processing it as usual with \LaTeX.
By processing your document the changed text is layouted as you stated by the corresponding options and/or special commands.

\minisec{output list of changes}

You can print a list of changes using:

\chcommand{listofchanges[style=<list|summary>]}

The list is meant to be the analogon to the list of tables, or the list of figures.

Stating the style is optional, default is \choption{style=list}.
In order to print a quick overview of the number and kind of changes of every author, use the option \choption{style=summary}.

By running \LaTeX\ the data of the list is written into an auxiliary file.
This data is used in the next \LaTeX\ run for typesetting the list of changes.
Therefore, two \LaTeX\ runs are needed after every change in order to typeset an up-to-date list of changes.


\minisec{remove markup}

Often you want to remove the change markup after acknowledging or rejecting the changes.
You can suppress the output of changes with:

\chcommand{usepackage[final]\{changes\}}

\subsection{Available scripts}

In order to remove the markup from the \LaTeX\ source code  you can use a script from Silvano Chiaradonna.
You find the script in the directory:

\texttt{<texpath>/scripts/changes/}

The script removes all markups.
You can select or deselect markup from removal using the interactive mode.
Switch on the interactive mode with the script parameter \texttt{-i}.

%^^A ---- limitations
\section{Limitations and possible enhancements}
\label{sec:limitations}

The \chpackage{changes}-package was carefully programmed and tested.
Yet the possibility of errors in the package exists, you might encounter problem during use, or you might miss functionionality.
In that case, please go to

\url{http://changes.sourceforge.net/}

There you can report errors, ask for help in the forum, or give advice to other users.
You can view the source code, and change it according to your needs.
I will try to include your changes in the maintained package.
If you are a registered \emph{sourceforge} user you can be a co-author of the \chpackage{changes}-package.

You can write me an email too, please send it to \href{mailto:ekleinod@edgesoft.de}{ekleinod@edgesoft.de}.
In that case, please start your email subject with \texttt{[changes]}.

Change markup of texts works well, it is possible to markup whole paragraphs.
You can markup more than one paragraph at a time but occasionally this leads to errors.
You cannot markup figures or tables.

You can try putting such text in an extra file and include in with \texttt{input}.
This works sometimes, give it a try.
Kudos to Charly Arenz for this tip.

There is a problem of typesetting footnotes in special environments, such as tables or tabbings.
Since footnotes are the default markup of remarks, this would be a problem.
You can solve this problem by defining another annotation of remarks.

There are several possibilities of enhancing the \chpackage{changes}-package.
I will describe but a few here, I will not implement them due to lack of time and/or skill.
You can have a look at the more complete list of enhancements on the \emph{sourceforge} page.

\begin{itemize}
	\item selecting of acknowledged and rejected texts; deletion of the corresponding markup
	\item markup of more than one paragraph
	\item markup of figures and tables
	\item automatic markup based on diff information (with regard to the limitations, such as markup of paragraphs, figures etc.)
	\item translation of language dependent texts and the user documentation in other languages
\end{itemize}


%^^A ---- user interface
\section{User interface of the \chpackage{changes}-package}
\label{sec:user}

This section describes the user interface of the \chpackage{changes}-package, i.e. all options and commands of the package.
Every option respectively new command is described.
If you want to see the options and commands in action, please refer to the examples in

\texttt{<texpath>/doc/latex/changes/examples/}

The example files are named with the used option respectively command.

A preliminary remark regarding typesetting of replaced text: replaced text is always typeset as follows: \meta{new text}\meta{old text}.
Thus, there is no possiblity to influence the output of replaced text directly, but via changing the output of added respectively deleted text.


%^^A -- options

The \choption{draft}-option enables markup of changes.

\subsubsection{final}
The \choption{final}-option disables markup of changes, only the correct text will be shown.
The list of changes is disabled, too.

The \chpackage{changes} package reuses the declaration of \choption{final} in \chcommand{documentclass}.

\subsection{Change management}
\label{sec:user:changemanagement}

\subsubsection{\chcommand{added}}
\DescribeMacro{\added}

The command \chcommand{added} marks new text.
The new text is the mandatory argument for the command, thus it is written in curly braces.
The optional argument contains key-value-pairs for author-id and remark.
The author-id has to be defined using \chcommand{definechangesauthor}.
If the remark contains special characters or spaces, use curly brackets to enclose the remark.

Therefore you need two \LaTeX-runs for an up-to-date list of changes.

The\marginpar{new since v2.0.0} style argument is optional, by default the list of changes is printed.
If you want to print a summary you have to use the option \choption{style=summary}.

\begin{chusage}
		\>\chcommand{listofchanges[style=<list|summary>]}

You have to define a unique author's id, special characters or spaces are not allowed within the author's id.
You may define a corresponding color and the author's name.
If you do not define a color, black is used.
The author's name is used in the list of changes and in the markup, if you set the corresponding option.

\begin{chusage}
		\>\chcommand{definechangesauthor[name=\{\meta{author's name}\}, color=\{\meta{color}\}]\{\meta{author's id}\}}\\
