Who are we ? What do wo do ?
First, we are french. Which is not really important except that our mother language has a large and precise set of typographic rules. This is the reason why we developed and manage the Markdown Extended package.
Finally, we support the open source concept. That is the reason why we developed a Bash library, a own PHP framework (well, thin and very simple but it works fine ;) and a lot of other packages under open source licences.
