/* GET_CONFIRMATION <description>
This command may be used to ask for a simple confirmation.
DESCRIPTION is displayed along with a Okay and Cancel button. This
command uses a syntax which helps clients to use the agent with
minimum effort. The agent either returns with an error or with a
OK. Note, that the length of DESCRIPTION is implicitly limited by
the maximum length of a command. DESCRIPTION should not conmtain
ant spaces, those must be encoded either percent escaped or simply
as '+'.
