 ## Introduction

+This is not a LaTeX package but a collection of libraries for PGF and TikZ;
 
-These are
-
- * `ext.calendar-plus`
- * `ext.node-families`
+ * `ext.calendar-plus` extends the `calendar` library with more tests, week numbers and a few goodies.
+ * `ext.layers` allows to put nodes etc on a separate layer without having to use `pgfonlayer`.
+ * `ext.nodes` extends the functionalities around nodes.
+ * `ext.node-families` uses the AUX file to sync the sizes of nodes.
     * `ext.node-families.shapes.geometric`
- * `ext.paths.arcto`
- * `ext.paths.ortho`
- * `ext.paths.timer`
- * `ext.patterns.images`
- * `ext.positioning-plus`
- * `ext.topaths.arcthrough`
- * `ext.transformations.mirror`
- * `ext.misc`
+ * `ext.paths.arcto` uses `\pgfpatharcto` to construct an arc *to* a point.
+ * `ext.paths.ortho` provides orthogonal path operations `-|-`, `|-|`, `r-rl`, `r-lr`, `r-du` and `r-ud`.
+ * `ext.paths.timer` adds timers to `rectangle`, `parabola`, `sin` and `cos`.
+ * `ext.patterns.images` allows images to be used as a path‘s pattern.
+ * `ext.positioning-plus` adds more ways to position nodes in reference to each other.
+ * `ext.scalepicture` scales a TikZ picture to the desired dimensions.
+ * `ext.topaths.arcthrough` installs a `to path` that expects a third point that defines an arc.
+ * `ext.transformations.mirror` adds transformations that reflect on arbitrary lines.
+ * `ext.misc` which includes
+   * the PGFKeys library `ext.pgfkeys-plus` and
+   * the PGFFor extension `pgffor-ext`.
  * Shapes:
    * `ext.shapes.circlearrow`
    * `ext.shapes.circlecrosssplit`
    * `ext.shapes.heatmark`
    * `ext.shapes.rectangleroundedcorners`

+\inspiration{NodesOnLine-Q, NodesOnCurve-Q}{NodesOnLine-A, NodesOnCurve-A}
+\end{tikzlibrary}
+
+\begin{multicols}{2}
+
+\subsection{Pic as a node}
+\begin{key}{/tikz/pic=\opt{\meta{boolean}} (default true, initially false)}
+This key allows one to use a pic where usually only nodes are accepted,
+for example as a label.
+\begin{codeexample}[preamble=\usetikzlibrary{ext.nodes, ext.misc}]
+\begin{tikzpicture}[
+  slsl/.pic={\draw (-2pt, 1.5pt) -- (2pt, .5pt)
+                   (2pt, -1.5pt) -- (-2pt, -.5pt);}]

+     label={[pic, rotate=90] north:slsl},
+     label={[pic            ] west:slsl},
+     label={[pic, rotate=-90]south:slsl}]{};
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+
+\subsection{Nodes on paths}
+When nodes are placed along paths they don't interrupt
+the path at that place.
+The decoration \referenceLibraryandIndexO{markings}
+and its \referenceKeyandIndexO[/pgf/decoration/]{mark connection node}
+key can help but only works for straight paths and
+doesn't play nicely with arrow tips.
+
+This library provides alternatives.
+These are separated into straight paths, i.\,e. \referencePathOperationandIndexO{--},
+and everything else (including any |to path|).
+
+\subsubsection{Nodes on Lines}
+
+\begin{stylekey}{/tikz/node on line=\opt{\meta{anchor specification}} (default |\{\}|)}
+This installs a \referenceKeyandIndexO{to path} that places \emph{one}
+node along a straight line but connect the line with it.
+
+This allows a node to be placed \emph{on} a straight line without having to
+use |fill = white| or similar tricks to make the line disappear 
+beneath the node.
+
+The optional \meta{anchor specification} allows to specify the
+anchors to which the line should connect.
+It allows one or two anchors divided by | and | to be specified.
+\end{stylekey}
+
+\begin{stylekey}{/tikz/nodes on line}
+This is similar to the previous key but allows
+multiple nodes to be placed on a straight line
+\emph{if} they are in the correct order (from start to target),
+don't overlap with each other, the start or the target.
+
+It allows \emph{no} anchor specification.
+\end{stylekey}
+
+\begin{codeexample}[preamble=\usetikzlibrary{ext.nodes, quotes}]
+\tikz[inner sep=.15em, circle, nodes=draw, sloped]
+  \draw[ultra thick, ->, node on line] (0,0) to["0"] (1,1)

+           to["1"] (2,0)
+           to["2"] (4,1);
+\end{codeexample}
+
+\subsubsection{Nodes on Curves}
+The following keys need the \referenceLibraryandIndexO{intersections}
+and the \referenceLibraryandIndexExt{spath3} \cite{spath3}
+library to be loaded. They will not be automatically
+loaded by this library.
+
+Any \referenceKeyandIndexO[/pgf/]{outer sep} will be ignored.
+
+If you can, use \texttt{fill=\meta{bg color}}
+instead of these keys, it will be much faster and easier.
+
+\begin{stylekey}{/tikz/nodes on curve=\meta{to path} (default line to)}
+Similar to \referenceKeyandIndex{nodes on line}, this key allows
+to have nodes on arbitrary paths.

+This key can be used to specify a \referencePackageandIndeXExt{xparse}

+
+For this to work somewhat seamless, the following needs to observed:
+\begin{itemize}
+  \item Every \marg{argument specification} get appended |u,|.
+        This means there's always one additional mandatory argument at the end of every element.
+  \item The \marg{foreach value} needs to correspond to the
+        \referenceKeyandIndexO[/pgf/foreach/]{var}
+        value.
+\end{itemize}
+\end{key}
+
+\begin{key}{/pgf/foreach/xparser Om}
+Sets up a list whose elements may contain an optional argment inside |[]| which correspond to
+two |\foreach| variables, say |\Options/\Text|.
+\end{key}
+
+\begin{handler}{{.list xparse}|=|\marg{argument specification}\marg{comma-separated list of values}}
+  This handler causes the key to be used repeatedly, namely
+  once for every element of the list of values.
+  The \meta{comma-separated list of values} is processed using |\foreach|
+  and the given |xparse| \meta{argument specification} with the aforementioned |xparser| key.
