Library for easily querying DNS SRV records

 RULI stands for Resolver User Layer Interface. It's a library
 built on top of an asynchronous DNS stub resolver. RULI
 provides an easy-to-use interface for querying DNS SRV
 resource records. The goal is to promote the wide deployment
 of SRV-cognizant client programs. RULI aims to fully support
 SRV-related standards.
