OpenSLP libraries
 Service Location Protocol is a IETF standard protocol that is used to
 discover/advertise services on the network. You can use SLP for anything
 from locating a suitable printer on your floor to discovering what LDAP
 directories are available in your organization. This package provides
 the OpenSLP run-time library package that is linked to SLP aware
 applications. This library implements RFC 2614 - An API for Service
 Location. Unless there is a SLP DA in the network, you must install the
 slpd package to be able to advertise the services.
