Zbigniew Jędrzejewski-Szmek 7d6b27238f man: xinclude the generic text to talk about libsystemd pkgconfig
The only difference is that functions are not individually listed by name,
but that seems completely pointless, since all functions that are documented
are always exported, so the generic text tells the user all she or he needs
to know.

<title>Description</title>
<para><function>sd_bus_message_set_destination()</function> sets the destination service name for the specified bus
message object. The specified name must be a valid unique or well-known service name.</para>
<para><function>sd_bus_message_set_sender()</function> sets the sender service name for the specified bus message
object. The specified name must be a valid unique or well-known service name. This function is useful only for
messages to send on direct connections as for connections to bus brokers the broker will fill in the destination
field anyway, and the sender field set by original sender is ignored.</para>
