• wiki addresses general texts, marked up in the simple style used on Wikipedia;
• niceverb is yet another means of documenting LaTeX packages: it offers syntax-aware typesetting of meta-variables (macro arguments) and for referring to commands (and their syntax) in footnotes, section titles etc.;
• fifinddo aims to parse plain text or (La)TeX files using TeX, and to write the results to an external file; the package is used by another member of the bundle:
• makedoc, which provides the means to produce typeset documentation direct from package files.
