-% todo: pass color for tracing
-
-%D This module is specially made for the oriental \TEX\ project. The working is as
-%D follows (and tuned for fonts like Idris' Husayni. The following method came to
-%D my mind after a couple of Skype sessions with Idris while working on the rough
-%D edges of the Husayni font and playing with font dynamics.
-%D
-%D \startitemize[packed]
-%D
-%D \item We define a couple of features sets, some can have stylistics variants
-%D       that result in the same words getting a different width. Normally this
-%D       happens in a goodies file.
-%D
-%D \item We group such features in a solution set. A solutionset can be enabled
-%D       by setting an attribute.
-%D
-%D \item For each paragraph we identify words that get this set applied. We replace
-%D       these words by a user node that refers to the original.
-%D
-%D \item For each word we apply the features to a copy that we associate with this
-%D       original word.
-%D
-%D \item At the end we have a paragraph (node list) with user nodes that point to a
-%D       cache that has originals and processed variants.
-%D
-%D \item When the paragraph is broken into lines we optimize the spacing by
-%D       substituting variants.
-%D
-%D \stopitemize
-%D
-%D This approach permits us to use a dedicated paragraph builder, one that treats
-%D the user nodes special and takes the alternatives into account.
-%D
-%D Currently we assume only one solution being active. Maybe some day I'll support
-%D a mixture. This is only one way of optimizing and after several experiments this
-%D one was chosen as testcase. It took quite some experiments (and time) to get thus
-%D far.
-%D
-%D The is experimental code for the Oriental \TEX\ project and aspects of it might
-%D change.

+%D This module is specially made for the oriental \TEX\ project. The working is as
+%D follows (and tuned for fonts like Idris' Husayni. The following method came to
+%D my mind after a couple of Skype sessions with Idris while working on the rough
+%D edges of the Husayni font and playing with font dynamics.
+%D
+%D \startitemize[packed]
+%D
+%D \item We define a couple of features sets, some can have stylistics variants
+%D       that result in the same words getting a different width. Normally this
+%D       happens in a goodies file.
+%D
+%D \item We group such features in a solution set. A solutionset can be enabled
+%D       by setting an attribute.
+%D
+%D \item For each paragraph we identify words that get this set applied. We replace
+%D       these words by a user node that refers to the original.
+%D
+%D \item For each word we apply the features to a copy that we associate with this
+%D       original word.
+%D
+%D \item At the end we have a paragraph (node list) with user nodes that point to a
+%D       cache that has originals and processed variants.
+%D
+%D \item When the paragraph is broken into lines we optimize the spacing by
+%D       substituting variants.
+%D
+%D \stopitemize
+%D
+%D This approach permits us to use a dedicated paragraph builder, one that treats
+%D the user nodes special and takes the alternatives into account.
+%D
+%D Currently we assume only one solution being active. Maybe some day I'll support
+%D a mixture. This is only one way of optimizing and after several experiments this
+%D one was chosen as testcase. It took quite some experiments (and time) to get thus
+%D far.
+%D
+%D The is experimental code for the Oriental \TEX\ project and aspects of it might
+%D change.

+%D optionally manipulate them and scale then next. Lookups are to be done as efficient
+%D as possible and inclusion of the data might happens only once. In \MKIV\ much of this
+%D is delegated to the \LUA\ end. There is nor so much less code as in \MKII\ but it's
+%D more powerful, flexible, pluggable and some of the extended functionality has been
+%D moved from modules to the core. The overall functionality is rather stable and has
+%D not changed much over the years.

+-- This module started out in the early days of mkiv and luatex with

+-- only a subset of the old visual debugger makes sense it has become a
+-- different implementation. Soms of the m-visual functionality will also
+-- be ported. The code is rather trivial. The caching is not really needed
+-- but saves upto 50% of the time needed to add visualization. Of course
+-- the overall runtime is larger because of color and layer processing in
+-- the backend (can be times as much) so the runtime is somewhat larger
+-- with full visualization enabled. In practice this will never happen

+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D The old visual debugger dates from 1996 and started out as joke. In practice
+%D it's not used that often although the \type {\ruledhbox} cum suis macros come
+%D in handy when writing code. In the process of luafication some additional
+%D tracing options were tested, for instance showing font kerns. As part of the
+%D \MKIV\ cleanup the decision was made to reimplement, reintegrate and reconsider
+%D all these features. The old code is gone and the new code will get extended
+%D when needed. We still provide placeholders for some old visualization commands
+%D but they might go away.
+%D
+%D Control over what gets visualized happens with the tracker command:
+%D
+%D \enabletrackers[...]
+%D
+%D Possible values are: \type {fontkern}, \type {kern}, \type {glue}, \type
+%D {penalty}, \type {hbox}, \type {vbox}, \type {all}, \type {reset}, \type
+%D {makeup}.
+%D
+%D In due time some special visualzation of math will move here as well.
