-% All the user input comes into the system in steps~\ref{step:parsing-bracket} (the
-% hierarchical structure) and \ref{step:given-options} (the content). The package does its work in
-% step~\ref{step:stages}, which consists of four \emph{stages}, where the work is really done, and
-% hooks before and after each stage, which provide a way to fine-tune the workflow.
-%
-% By default, the \keyname{after ...} hooks do nothing, and the \keyname{before ...} hooks process
-% the deferred keylists. For a simple example, see
-% example~\ref{ex:adjustxy}: the manual adjustment of \ikeyname{y} can only be done after the
-% absolute positions have been computed, so the processing of this option is deferred by
-% \ikeyname{before drawing tree}. For a more realistic example, see the definition of style
-% \ikeyname{GP1}:
-% before packing, \texttt{outer xsep} is set to a high (user determined) value to keep the $\times$s
-% uniformly spaced; before drawing the tree, the \texttt{outer xsep} is set to \texttt{0pt} to make
-% the arrows look better.
+% Steps~\ref{step:parsing-bracket} and \ref{step:given-options} collect user input and are thus
+% ``fixed''. However, the other steps, which do the actual work, are under user's control.
+%
+% First, hooks exist which make it possible (and easy) to change node's properties between the
+% processing stages. For a simple example, see example~\ref{ex:adjustxy}: the manual adjustment of
+% \ikeyname{y} can only be done after the absolute positions have been computed, so the processing
+% of this option is deferred by \ikeyname{before drawing tree}. For a more realistic example, see
+% the definition of style \ikeyname{GP1}: before packing, \texttt{outer xsep} is set to a high (user
+% determined) value to keep the $\times$s uniformly spaced; before drawing the tree, the
+% \texttt{outer xsep} is set to \texttt{0pt} to make the arrows look better.
%
-% Style
-% \ikeyname{stages} and the hook styles can be redefined. Obviously, a style must be redefined
-% before it is processed, so its safest to do so either outside the
-% \ikeyname{forest} environment using macro \icmdname{forestset}, or in
-% stage~\ref{step:given-options} among the non-deferred keys. The following keys might be useful
-% in a redefinition. (\ikeyname{typeset nodes}, \ikeyname{pack} and \ikeyname{compute xy} are not
-% included in the list, since they were already fully described above.)
+% Second, the execution of the processing stages \ref{step:typeset-nodes}--\ref{step:draw-tree} is
+% \emph{completely} under user's control. To facilitate adjusting the processing flow, the approach
+% is twofold. The outer level: \foRest; initiates the processing by executing style
+% \keyname{stages}, which by default executes the processing stages
+% \ref{step:typeset-nodes}--\ref{step:draw-tree}, preceding the execution of each stage by
+% processing the options embedded in temporal propagators \keyname{before ...} (see
+% \S\ref{ref:propagators}). The inner level: each processing step is the sole resident of a
+% stage-style, which makes it easy to adjust the workings of a single step. What follows is the
+% default content of style \keyname{stages}, including the default content of the individual
+% stage-styles.
% \begin{syntax}

-% Using this key \emph{is} compatible with externalization.
+% Both style \keyname{stages} and the individual stage-styles may be freely modified by the user.

+% (in a non-deferred fashion).
+%
+% Here's the list of keys used either in the default processing or useful in an alternative
+% processing flow.
+% \begin{syntax}
+% \rkeyname[item]{typeset nodes} Typesets each node of the current node's subtree in its own
+% |tikzpicture| environment. The result is saved in a box and its measures are taken.
+%

-% overwritten if it already exists.
+% overwritten if the box already exists.
+%
% \rkeyname[item]{typeset node} Typesets the \emph{current} node, saving the result in the node box.
%
% This key can be useful also in the default \ikeyname{stages}. If, for example, the node's content
% is changed and the node retypeset just before drawing the tree, the node will be positioned as if
% it contained the ``old'' content, but have the new content: this is how the constant distance
% between $\times$s is implemented in the \ikeyname{GP1} style.
+%
+% \rkeyname[item]{pack} The nodes of the tree are \emph{packed}, i.e.\ the relative positions of
+% the nodes are computed so that the nodes don't overlap. The result: option \ikeyname{s} is set
+% for all nodes; sometimes (in tier alignment and for some values of \ikeyname{calign}), the value
+% of some nodes' \ikeyname{l} is adjusted as well.
+%
+% \rkeyname[item]{pack'} ``Non-recursive'' packing: packs the children of the current node only.
+% (Experimental, use with care, especially when combining with tier alignment.)
+%
+% \rkeyname[item]{compute xy} Computes the positions of the nodes relative to the (formal) root
+% node. The results are stored into options \ikeyname{x} and \ikeyname{y}.
+%
+% \rkeyname[item]{draw tree} Produces the \TikZ; code that will draw the tree. First, any
+% \TikZ; code given by \ikeyname{tikz preamble} is included. Then, the nodes are drawn (using the
+% boxes typeset in step~\ref{step:typeset-nodes}), followed by edges and custom code (see option
+% \ikeyname{tikz}).

+% \rkeyname[item]{draw tree'} Like \ikeyname{draw tree}, but the node boxes are included in the
