\section{License and Requirements}\label{sec:license}\secidx{License}
\snotez is placed under the terms of the \LaTeX{} Project Public License,
version 1.3 or later (\url{http://www.latex-project.org/lppl.txt}). It has the
status ``maintained.''

\snotez needs and loads the packages
\paket*{etoolbox}\sidenote[*-2][]{\textcite{pkg:etoolbox}},
\paket*{pgfopts}\sidenote[*-][]{\textcite{pkg:pgfopts}},
\paket*{marginnote}\sidenote{\textcite{pkg:marginnote}} and
\paket*{perpage}\sidenote{\textcite{pkg:perpage}}.
\secidx*{License}

\section{Motivation}
This has just been an exercise on a lazy
afternoon\sidenote[*-2][]{\url{http://www.youtube.com/watch?v=PPRiaYH1iTk}}.
Well, more or less at least. Since there already is Andy Thomas' \paket*{sidenotes}
package\sidenote[*-][]{\textcite{pkg:sidenotes}} there is probably
no real need for \snotez. Moreover, the tufte classes\sidenote{\textcite{cls:tufte}}
as well as \klasse{memoir}\sidenote{\textcite{cls:memoir}} also provide corresponding
mechanisms. Besides the fun I had my motivation was also based on the fact that
I didn't like some smaller things (\emph{not} bugs) done by the \paket{sidenotes}
package such as inserting kerns and superscripted commas for multiple marks. I
prefer to let my \paket*{fnpct}\sidenote{\textcite{pkg:fnpct}} package handle
these things. Anyways, here it is and it seems to be working as intended so I
don't see a reason why it shouldn't be available for use.

By the way: the \paket*{fnpct} package v0.2k and later knows about \snotez and
automatically adapts the note commands. Please note that you need to enable
the \key{dblarg} option (see page~\pageref{key:dblarg}) when you're using
\paket*{fnpct} together with \snotez!

\section{Introduction}\secidx{Introduction}
The \snotez Package introduces a \cmd{sidenote} command%
\begingroup\defaultsidenotes
\sidenote{This is an example demonstrating the default appearance.}
\endgroup
that typesets sidenotes the
same way \cmd{footnote} typesets footnotes. It provides some options that allow
formatting the appearance of the sidenotes\sidenote[*][]{In all sidenotes in this
document the mark is typeset on the baseline and the text is set ragged right.}.
As a default sidenotes are typeset in a \cmd{marginpar} but there are possibilities
using Markus Kohm's \paket{marginnote}~\cite{pkg:marginnote} package as well.

As with footnotes it is possible to set mark and text separately using the
equivalent commands \cmd{sidenotemark} and \cmd{sidenotetext}, respectively.
Instead of lots of code examples this documentation will use the \cmd{sidenote}
macro itself extensively. It is assumend you know how to use \cmd{footnote} and
are able to transfer your knowledge.
\secidx*{Introduction}

\section{Usage}\secidx{Usage}
The basic usage is the very same as with \LaTeX's \cmd{footnote}, \cmd{footnotemark}
and \cmd{footnotetext}. Unsurprisingly the presented commands are these:
\begin{beschreibung}
 \Befehl{sidenote}\oa{<mark>}\ma{<text>}\newline
   The basic command. The syntax is the very same as for \cmd{footnote}.
 \Befehl{sidenote}\oa{<offset>}\oa{<mark>}\ma{<text>}\newline
   Actually I lied: \cmd{sidenote} has a second option that smuggles itself
   before the \oa{<mark>} option if you use it: an argument for a vertical offset
   that takes a length. An empty second option assumes you want the automatic
   mark. If you use this argument the note is set with the \cmd{marginnote}
   command\sidenote[*-3][]{From the \paket{marginnote} package}.
   Please see its documentation\sidenote[*-2][]{For example with \texttt{texdoc
   marginnote} on your command line.}~\cite{pkg:marginnote} for the \da{<offset>}
   argument. \snotez only passes the value on.\par
   \sinceversion{0.3} Actually, this is only part of the truth: while typing this
   documentation I repeatedly found myself shifting notes by multiples of
   \cmd{baselineskip} so the argument accepts a shortcut for this. A star \code{*}
   followed by a (positive or negative) number denotes a multiple of \cmd{baselineskip}.
   By the way: a positive value shifts the note \emph{down}.\par
   When you're using the \key{dblarg}{false} option this second optional argument
   has parentheses instead of square brackets!
 \Befehl{sidenotemark}\oa{<text>}\newline
   This command has the same purpose as \cmd{footnotemark} but for sidenotes.
 \Befehl{sidenotetext}\oa{<mark>}\ma{<text>}\newline
   The same as \cmd{footnotetext} but for sidenotes. Beware where you place it:
   it calls \cmd{marginpar} or \cmd{marginnote} and thus determines where the
   actual note is placed.
 \Befehl{sidenotetext}\oa{<offset>}\oa{<mark>}\ma{<text>}\newline
   I lied again: \cmd{sidenotetext} also has the second optional argument
   \oa{<offset>} that again smuggles itself before the \oa{<mark>} option if you
   use it. For details see the second description of the \cmd{sidenote} command.
\end{beschreibung}

Here is one short example of the usage.

\begin{beispiel}[code only]
 % produces a sidenote with automatic number in a
 % \marginpar:
 \sidenote{A note}

 % produces a sidenote with mark `a' in a
 % \marginpar:
 \sidenote[a]{A note}

 % produces a sidenote with automatic number in a
 % \marginnote:
 \sidenote[][]{A note}
 % alternative syntax (dblarg=false):
 \sidenote(){A note}

 % produces a sidenote with automatic number in a
 % \marginnote shifted down by \baselineskip:
 \sidenote[*][]{A note}
 % alternative syntax (dblarg=false):
 \sidenote(*){A note}

 % produces a sidenote with automatic number in a
 % \marginnote shifted up by 2ex:
 \sidenote[-2ex][]{A note}
 % alternative syntax (dblarg=false):
 \sidenote(-2ex){A note}

 % produces a sidenote with mark `a' in a
 % \marginnote shifted down by 2\baselineskip:
 \sidenote[*2][a]{A note}
 % alternative syntax (dblarg=false):
 \sidenote(*2)[a]{A note}
\end{beispiel}
\secidx*{Usage}

\section{Options}\secidx{Options}
Although all options can be used as package option you can also set all options
(locally) with a setup command:
\begin{beschreibung}
 \Befehl{setsidenotes}{<options>}
\end{beschreibung}
Available options are these:
\begin{beschreibung}
 \Option{dblarg}{\default{true}|false}\Default{true}
   \sinceversion{0.3}\emph{This option can only be used as a package option!}
   Prior to version~0.3 \snotez' \cmd{sidenote} and \cmd{sidenotetext} had both
   their optional arguments with square brackets where the use of one argument
   referred to the mark but when both were used the first argument referred to
   the offset and the second to the mark. This syntax is kept with this option.
   Setting it to \code{false} changes the \oa{<offset>} argument syntax into
   \da{<offset>}.\par
   \emph{If you're using \snotez together with the \paket*{fnpct} package~\cite{pkg:fnpct}
   you cannot set \key{dblarg} to \code{false}. Otherwise the \da{<offset>}
   argument get's lost!}
 \Option{marginnote}{\default{true}|false}\Default{false}
   Use \paket{marginnote}'s \cmd{marginnote}~\cite{pkg:marginnote} for all
   \cmd{sidenote}s. In the default setting \cmd{sidenote} uses \cmd{marginpar}s
   to set the sidenote unless you use the \oa{<offset>} argument. If you use
   this option \emph{all} sidenotes are set with \cmd{marginnote}. \emph{This
   option can only be used in the preamble}.
 \Option{text-format}{<code>}\Default{\cmd*{footnotesize}}
   The format of the sidenote text.
 \Option{text-format+}{<code>}\Default{}
   Code to be appended to the format set with \key{text-format}\sidenote{This
   document, for example, appends \paket*{ragged2e}'s \cmd*{RaggedRight}~\cite{pkg:ragged2e}
   to the sidenote's format.}.
 \Option{perpage}{\default{true}|false}\Default{false}
   Make sidenotes counter per page. \emph{This option can only be set in the
   preamble}. It uses package \paket{perpage}'s~\cite{pkg:perpage}
   \cmd{MakeSortedPerPage} macro for the task. Otherwise the macro
   \cmd{MakeSorted} is used. In the default setting sidenotes are counted per
   chapter. If you want sidenotes counted document-wise together with a class
   that defines a counter \code{chapter} then use for example the package
   \paket*{chngcntr}~\cite{pkg:chngcntr} and issue
   \cmd*{counterwithout}{sidenote}\ma{chapter} after loading \snotez.
   This documentation is an example for the use of the option.
 \Option{note-mark-sep}{<code>}\Default{\cmd*{space}}
   The separator between sidenote mark and sidenote text in the sidenote.
 \Option{note-mark-format}{<code>}\Default{\cmd*{@textsuperscript}\{\cmd*{normalfont}\#1\}}
   The format of the sidenote mark in the sidenote. Please refer to the actual
   mark with \code{\#1}.
 \Option{text-mark-format}{<code>}\Default{\cmd*{@textsuperscript}\{\cmd*{normalfont}\#1\}}
   The format of the sidenote mark in the text\sidenote[*-][]{This document uses
   Michael Sharpe's \paket*{superiors} package~\cite{pkg:superiors} and redefines
   the mark formats to use its \cmd*{textsu} command.}. Please refer to the actual
   mark with \code{\#1}.
 \Option{footnote}{\default{true}|false}\Default{false}
   Let\sidenote[*][]{In the sense of \cmd*{let}} \cmd{footnote} to be \cmd{sidenote},
   \cmd{footnotemark} to be \cmd{sidenotemark} and \cmd{footnotetext} to be
   \cmd{sidenotetext}. \emph{This option can only be used in the preamble}.
\end{beschreibung}

As a short example this is how the sidenotes for this document are formatted:
\begin{beispiel}[code only]
\setsidenotes{
  note-mark-format=#1.,
  text-mark-format=\textsu{\hspace*{\superiors@spaced}#1},
  text-format+=\RaggedRight,
  perpage=true
}
