{Documentation in \TeX{}nicolor} {Federico Garcia} {My package \code{colordoc} builds on Frank Mittelbach's \code{docstrip} system of documentation, adding some utilities to use color in the code: matching delimiters (\code{\char`{} and \code{\char`}}) are colored the same, just as matching \cs{if}--\cs{fi} pairs. Commands are made red, bold, and italics, when they are being \cs{def}\,ined, just as variables when they are being declared (\cs{newcount}, \cs{newif}, etc.). These tools have certainly saved me a lot of time and trouble when editing or trying to understand a code. In the presentation I also describe the interesting general lines of the workings of both \code{doc} and \code{colordoc}. }
