Place this message in repos that should be unused. Bad repos. Repos with scripts that convert yaml to xml.
This README is a message… and part of a system of messages …pay attention to it! Sending this message was important to us. We considered ourselves to be a powerful culture. This repo is not a place of honor… no highly esteemed deed is commemorated here… nothing valued is here. What is here was dangerous and repulsive to us. This message is a warning about danger. The danger is in these files… it increases towards later commits… the center of danger is at commit <X>… of a particular <sha1>. The danger is still present, in your time, as it was in ours. The danger is to the mind, and it can fuck up your day. The form of the danger is an emanation of bullshit. The danger is unleashed only if you check out the files. This repo is best shunned and left unforked.
