 \def\command#1{\item[\ttfamily \color{blue} \textbackslash#1]}
+\command{allownumberincommands} Normally, you cannot use numbers as part of a control sequence (or, command) name. This makes perfect sense and is good as it is. However, just to raise awareness to this, we provide a command here that changes the chategory codes of numbers 0–9 to 11, i.\,e.~normal character. So they \emph{can} be used in command names. However, this will break many packages, so do \emph{not} expect anything to work! At least use it \emph{after} all packages are loaded.
 \command{boustrophedon} Reverts every second line. This immitates archaic greek writings where one line was right-to-left, the next one left-to-right etc.\footnote{\url{en.wikipedia.org/wiki/Boustrophedon}} Interestingly, also every glyph was adaptet to the writing direction, so all glyphs are inverted in the right-to-left lines. Actually, there are two versions of this command that differ in their implementation: |\boustrophedon| rotates the whole line, while |\boustrophedonglyphs| changes the writing direction and reverses glyph-wise. The second one takes much more compilation time, but may be more reliable. A Rongorongo\footnote{\url{en.wikipedia.org/wiki/Rongorongo}} similar style boustrophedon is available with |\boustrophedoninverse| or |\rongorongonize|, where subsequent lines are rotated by 180° instead of mirrored.
-\command{countglyphs} \textcolor{blue}{\texttt{\textbackslash countwords}} Counts every printed character (or word, respectively) that appeared in anything that is a paragraph. Which is quite everything, in fact, \emph{exept} math mode! The total number will be printed at the end of the log file/console output.
+\command{countglyphs} \textcolor{blue}{\texttt{\textbackslash countwords}} Counts every printed character (or word, respectively) that appears in anything that is a paragraph. Which is quite everything, in fact, \emph{exept} math mode! The total number of glyphs/words will be printed at the end of the log file/console output. For glyphs, also the number of use for every letter is printed separately.
 \command{chickenize} Replaces every word of the input with the word “chicken”. Maybe sometime the replacement will be made configurable, but up to now, it's only chicken. To be a bit less static, about every 10\textsuperscript{th} chicken is uppercase. However, the beginning of a sentence is not recognized automatically.\footnote{If you have a nice implementation idea, I'd love to include this!}
 \command{colorstretch} Inspired by Paul Isambert's code, this command prints boxes instead of lines. The greyness of the first (left-hand) box corresponds to the badness of the line, i.\,e. it is a measure for how much the space between words has been extended to get proper paragraph justification. The second box on the right-hand side shows the amount of stretching/shrinking when font expansion is used. Together, the greyness of both boxes indicate how well the greyness is distributed over the typeset page.

 \command{rainbowcolor} Instead of random colors, this command causes the text color to change gradually according to the colors of a rainbow. Do not mix this with |randomcolor|, as that doesn't make any sense.
 \command{pancakenize} This is a dummy command that does nothing. However, every time you use it, you owe a pancake to the package author. You can either send it via mail or bring it to some (local) \TeX\ user's group meeting.
-\command{substitutewords} You have to specify pairs of words by using |\addtosubstitutions{word1}{word2}|. Then call |\substitutewords| (or the other way round, doesn't matter) and each occurance of |word1| will be replaced by |word2|. You can add replacement pairs by repeated calls to |\addtosubstitutions|. Take care! This function warks with the input directly, therefore it does \emph{not} work on text that is inserted by macros, but it \emph{will} work on macro names itself! This way, you may use it to change macros (or environments) at will. Bug or feature? I'm not sure right now …

+\command{suppressonecharbreak} \TeX~normally does not suppress a linebreak after words with only one character (“I“, “a” etc.) This command suppresses line breaks. It is very similar to the code provided by the |impnattypo| package and based on the same ideas. However, the code in |chickenize| has been written before the author knew |impnattypo|, and the code differs a bit, might even be a bit faster. Well, test it!
 \command{tabularasa} Takes every glyph out of the document and replaces it by empty space of the same width. That could be useful if you want to hide some part of a text or similar. The |\text|-version is most likely more useful.
 \command{uppercasecolor} Makes every uppercase character in the input colored. At the moment, the color is randomized over the full rgb scale, but that will be adjustable once options are well implemented.
 \command{variantjustification} For special document types, it might be mandatory to have a fixed interword space. If you still want to have a justified type area, there must be another kind of stretchable material – one version realized by this command is using wide variants of glyphs to fill the remaining space. As the glyph substitution takes place randomly, this does \emph{not} provide the optimum justification, as this would take up much computation power.

 \section{Nodes}
 Essentially everything that Lua\TeX\ deals with are nodes – letters, spaces, colors, rules etc. In this package, we make heavy use of different types of nodes, so an understanding of the concept is crucial for the functionality.
 
-A node is an object that has different properties, depending on its type which is stored in its |.id| field. For example, a node of type |glyph| has |id| 37, has a number |.char| that represents its unicode codepoint, a |.font| entry that determines the font used for this glyph, a |.height|, |.depth| and |.width| etc.
+A node is an object that has different properties, depending on its type which is stored in its |.id| field. For example, a node of type |glyph| has |id| 27 (up to Lua\TeX~0.80., it was 37) has a number |.char| that represents its unicode codepoint, a |.font| entry that determines the font used for this glyph, a |.height|, |.depth| and |.width| etc.
 
 Also, a node typically has a non-empty field |.next| and |.prev|. In a list, these point to the – guess it – next or previous node. Using this, one can walk over a list of nodes step by step and manipulate the list.
 
-A more convenient way to adress each node of a list is the function |node.traverse(head)| which takes as first argument the first node of the list. However, often one wants to adress only a certain type of nodes in a list – e.\,g. all glyphs in a vertical list that also contains glue, rules etc. This is achieved by calling the function |node.traverse_id(37,head)|, with the first argument giving the respective id of the nodes.

This number can be achieved by calling |GLYPH = nodeid("glyph")| which will result in the correct number independent of the Lua\TeX~version. We will use this substitute throughout this docmuent.}
 
 The following example removes all characters “e” from the input just before paragraph breaking. This might not make any sense, but it is a good example anyways:
 \begin{verbatim}
 function remove_e(head)
-  for n in node.traverse_id(37,head) do
+  for n in node.traverse_id(GLYPH,head) do
     if n.char == 101 then
