long_desc <<-LONG_DESC
Crawl the fediverse by using the Mastodon REST API endpoints that expose
all known peers, and collect statistics from those peers, as long as those
peers support those API endpoints. When no START is given, the command uses
this server's own database of known peers to seed the crawl.
The --concurrency (-c) option controls the number of threads performing HTTP
requests at the same time. More threads means the crawl may complete faster.
The --silent (-s) option controls progress output.
The --format (-f) option controls how the data is displayed at the end. By
default (`summary`), a summary of the statistics is returned. The other options
are `domains`, which returns a newline-delimited list of all discovered peers,
and `json`, which dumps all the aggregated data raw.
