tala.run and its talac, tazel, talafmt and talalint hosts take the
rules progmasoft.com and tazel.net use: Googlebot, Google-Extended,
OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User and
ClaudeBot are allowed; GPTBot, CCBot and Bytespider are turned away;
every other crawler is allowed. The rules for PerplexityBot,
Perplexity-User, meta-externalagent, meta-externalfetcher, FacebookBot,
DuckAssistBot, Amazonbot, Google-CloudVertexBot and MistralAI-User go,
so they fall under the rule for every crawler. Each host keeps its own
sitemap.

The first -- ends the name of a custom command, and a line of s(...)
