(define-erc-module querypoll nil
  "Send periodic \"WHO\" requests for each query buffer.
Omit query participants who are currently present in some channel.
Instead of announcing arrivals and departures, rely on other modules,
like `nickbar', to provide UI feedback when changes occur.

Once ERC implements the `monitor' extension, this module will serve as
an optional fallback for keeping query-participant rolls up to date on
servers that lack support or are stingy with their allotments.  Until
such time, this module should be considered experimental.

This is a local ERC module, so selectively polling only a subset of
query targets is possible but cumbersome.  To do so, ensure
`erc-querypoll-mode' is enabled in the server buffer, and then toggle it
as appropriate in desired query buffers.  To stop polling for the
current connection, toggle off the command \\[erc-querypoll-mode] from a
server buffer, or run \\`M-x C-u erc-querypoll-disable RET' from a
target buffer."
