 \def\command#1{\item[\ttfamily \color{blue} \textbackslash#1]}
+\command{countglyphs} Counts every printed character 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{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{nyanize} A synonym for |rainbowcolor|.
 \command{matrixize} Replaces every glyph by a binary representation of its ASCII value.
 \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{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 …

+% This function is one of the rather usefull ones of this package. It replaces each occurance of one word by another word, which both are specified by the user. So nothing random or funny, but a real serious function! There are three levels for this function: At user-level, the user just specifies two strings that are passed to the function |addtosubstitutions|. This is needed as the |#| has a special meaning both in \TeX s definitions and in Lua. In this second step, the list of substitutions is just extended, and the real work is done by the function |substiuteword| which is registered in the |process_input_buffer| callback. Once the substitution list is built, the rest is very simple: We just use |gsub| to substitute, do this for every item in the list, and that's it.
