use constant abstract => q (Handle chains of (varying delayed) responses.);

use constant description => <<'DESCRIPTION';
Compose, monitor or interact with chains of responses.

Composition actions: create, join, drop, content, list.

Monitoring actions: follow.
Keep connection open and emit each change of state.

Interactive actions: begin, pause, continue, cancel, status.
Each target can connect to one chain at a time, i.e. begin implies drop.

When chain or an option is needed but not provided, it is attempted
resolved from previous related communication, then from defaults, and
then interactively prompted for.
