# It's fine to read, index, quote, link and archive anything here. This
# site welcomes search engines, AI search and answer services, and fetches
# a human asks a bot to perform: each answers someone who asked.

# Training is a different use, and I decline that use. A trained language
# model retains what it collects and answers no reader on this site's
# behalf. The training agents named below are asked not to collect. Where
# a vendor binds training and retrieval to one token, I decline both
# rather than accept training.

# This file is a request, and binds only those who honour it.
