($reason) is a string containing error message, or something like "OK" if status is
200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth
element (%result_meta) is called result metadata and is optional, a hash
that contains extra information, much like how HTTP response headers provide additional metadata.

Return value:  (any)



=head2 opera_is_running

Usage:

 opera_is_running(%args) -> [$status_code, $reason, $payload, \%result_meta]

Check whether Opera is running.

Opera is defined as running if there are some Opera processes that are I<not>
in 'stop' state. In other words, if Opera has been started but is currently
paused, we do not say that it's running. If you want to check if Opera process
exists, you can use C<ps_opera>.

Arguments ('*' denotes required arguments):

=over 4

=item * B<quiet> => I<true>

=item * B<users> => I<array[unix::uid::exists]>

Kill browser processes that belong to certain user(s) only.


=back

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code
(200 means OK, 4xx caller error, 5xx function error). Second element
($reason) is a string containing error message, or something like "OK" if status is
200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth
element (%result_meta) is called result metadata and is optional, a hash
that contains extra information, much like how HTTP response headers provide additional metadata.

Return value:  (any)



=head2 pause_opera

Usage:

 pause_opera(%args) -> [$status_code, $reason, $payload, \%result_meta]

Pause (kill -STOP) Opera.

A modern browser now runs complex web pages and applications. Despite browser's
power management feature, these pages/tabs on the browser often still eat
considerable CPU cycles even though they only run in the background. Pausing
(kill -STOP) the browser processes is a simple and effective way to stop CPU
eating on Unix and prolong your laptop battery life. It can be performed
whenever you are not using your browser for a little while, e.g. when you are
typing on an editor or watching a movie. When you want to use your browser
again, simply unpause (kill -CONT) it.
