OpenSLP shared library

 Service Location Protocol is an 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.
