\chapter{Introduction}

\type{Chronosys}  is distributed under the LaTeX Project Public License. It uses the \type{tikz} package for drawing the time-lines.
\blank

This package is version {\unprotect\chron@sysversion\protect}, anothers versions might be created later.
\bigskip
It is recommanded not to load the \type{color.tex} file if you use plain \TeX.
\bigskip

You can load \type{chronosys} by~:
\startitemize[4]
\item \type{\usemodule[chronosys]} in \CONTEXT.
\item \type{\usepackage{chronosys}} in \LaTeX.
\item \type{\input chronosys} in plain \TeX.
\stopitemize

\chapter{First use}

\section{Main fonction: \type{\startchronology}}

The control sequence \type{\startchronology}\index{startchronology} is the first one you need to know.\footnote{There are \type{\begin{chronology}} and \type{\end{chronology}} for \LaTeX}~: it starts the chronological frieze.
\blank[small]
The next one is \type{\stopchronology}\index{stopchronology}\footnote{or \type{\end{chronology}}}, it ends the time-line. Let's have a look on the result~:
\starttyping
\startchronology
\stopchronology\stoptyping

\startchronology
\stopchronology
\bigskip
You can see the time-line is on all the page's width, furthermore it starts at {\os0} and ends at the current year {\os\the\year} when this document was compiled. \type{Chronosys} will compare these years with the events and periods you will give him (see \in[event] and \in[period]).
\blank[small]Now let's learn how to add events on the time-line.

\section[event]{Events: \type{\chronoevent}}

You can add events with \type{\chronoevent}\index{chronoevent}. This control sequence needs two arguments: the first one is the date of the event\footnote{you can see further to see another way of specifying the date} and the second is the label of this event.

\blank[small]
For example:
\starttyping 
\startchronology
\chronoevent{1977}{\TeX's creation}
\stopchronology
\stoptyping
\startchronology
\chronoevent{1977}{\TeX's creation}
\stopchronology
\bigskip
The event appears between {\os 0} et {\os\the\year}, proportionally with his gap with {\os0}. You can also give several events:

\starttyping 
\startchronology
\chronoevent{476}{Fall of the Roman empire}
\chronoevent{1492}{Discovery of America}
\chronoevent{1969}{first steps on the Moon}
\stopchronology
\stoptyping

\switchtobodyfont[9pt]
\startchronology
\chronoevent{476}{Fall of the Roman empire}
\chronoevent{1492}{Discovery of America}
\chronoevent{1969}{first steps on the Moon}
\stopchronology
\switchtobodyfont[14pt]
\bigskip N.B.: the font size has been reduced to avoid label to overlap; a best way will be given further (see \in[eventoptions]).\blank

\type{Chronosys} won't generate any error if the event's date is out of the starting year and ending year, however it will be ignored. The way of customize 
the time-line, especially the starting year and ending year, will be seen further(see \in[startchronologyoptions]).

\section[period]{Periods: \type{\chronoperiode}}

You can also add one period (or several\footnote{If two periods are overlapping, the last one will overlap the other}) on the frieze with \type{\chronoperiode}\index{chronperiode}.

\starttyping
\startchronology
\chronoperiode{1000}{1999}{2\high{nd} Millennium}
\chronoperiode{476}{1453}{Eastern Roman Empire}
\chronoevent{1969}{first steps on the Moon}
\stopchronology
\stoptyping
\switchtobodyfont[9pt]
\startchronology
\chronoperiode{1000}{1999}{2\high{nd} Millennium}
\chronoperiode{14}{476}{Roman empire (without Augustus)}
\chronoevent{1969}{first steps on the Moon}
\stopchronology
\switchtobodyfont[14pt]
\blank
N.B.: on the period from {\os1000} to {\os1999}, blue on the time-line, we can now see the vertical straight under the frieze. You can disable it (see \in[eventoptions]), but if you want it you should place the events after the periods.

The period appears automatically with colour, and the dates are also visible (see \in[periodoptions] to disable them) and the label. The periods can be automatically coloured in 5 colours : blue, red, cyan, purple and yellow, except if the colour is identical to the frieze's one. Of course you can choose the colour of the period (see \in[periodoptions]). 

\chapter[Personnalisation]{Time-lines' customization}

\section{\type{\startchronology}}
\subsection{Example}
\type{\startchronology} can have an optional argument in brackets. 
For example:
\starttyping
\startchronology 
[startyear=-800,stopyear=500,color=darkblue,height=7ex,width=\hsize]
\chronoevent{-753}{Rome's foundation}
\stopchronology
\stoptyping
\startchronology 
[startyear=-800,stopyear=500,color=darkblue,height=7ex,width=\hsize]
\chronoevent{-753}{Rome's foundation}
\stopchronology
\bigskip

\section{\type{\chronoevent}}

\subsection[eventnewdate]{A new way for specifying the date}

You can specify with more precision the date with \type{\chronoevent}\index{chronoevent}. We saw that typing 
\type{\chronoevent{-44}{Assassination of Caesar}} specified the year of the event, now we will saw the way of specifying
the month and the day. You have to type \type{<day number>/<number of the month>/year}, only specifying the year is compulsory.

You can give only the year as we saw before, the number of the month and the year or the day number and the number of the month and the year. The number of the month is automatically converted to the name of the month (in french by default). You can disable this conversion (see \in[eventoptions]).The control sequence of conversion is:
\starttyping
\def\chron@selectmonth#1{\ifcase#1\or janvier\or f\'evrier\or
 mars\or avril\or mai\or juin\or juillet\or ao\^ut\or septembre\or
 octobre\or novembre\or d\'ecembre\fi}
\stoptyping

To change the language, you only need to redefine the control sequence, for example for english as:
\starttyping
\def\chron@selectmonth#1{\ifcase#1\or January\or February\or
 March\or April\or May\or June\or July\or August\or September\or
 October\or November\or December\fi}
\stoptyping
\bigskip
For example,
\starttyping
\catcode`\@=11
\def\chron@selectmonth#1{\ifcase#1\or January\or February\or
 March\or April\or May\or June\or July\or August\or September\or
 October\or November\or December\fi}
\startchronology[startyear=-44,stopyear=-43,color=darkgreen,height=7ex]
\chronoevent{15/03/-44}{Assassination of Caesar}
\stopchronology
\stoptyping
\catcode`\@=11
\def\chron@selectmonth#1{\ifcase#1\or January\or February\or
 March\or April\or May\or June\or July\or August\or September\or
 October\or November\or December\fi}

\startchronology[startyear=-44,stopyear=-43,color=darkgreen,height=7ex]
\chronoevent{15/03/-44}{Assassination of Caesar}
\stopchronology
\blank
Furthermore, \type{\chronoevent} can also have an optional argument for customization.
\subsection{Example}

\starttyping
\def\MyIcon{{\starttikzpicture \filldraw

\head \type{datesseparation}\index{datesseparation} : symbol of separation of each element of the date. It can be a control sequence or some text and is a space by default.
