From the Pharo 6 catalog:
Pillar is a wiki-like syntax, a document model, a parser for it, and a set of exporters (e.g., HTML, LaTeX, Markdown...). Pillar is primarily used as the wiki syntax behind the Pier CMS. Pillar is also being used to write books: e.g., the Enterprise Pharo book.
The original creator of Pillar (formerly known as ''the syntax behind the Pier CMS'') is Lukas Renggli. Nevertheless, Damien Cassou is now the maintainer. The website is at http://www.smalltalkhub.com/#!/~Pier/Pillar. Issues should be reported to https://github.com/pillar-markup/pillar/issues
