wrapsrv - DNS SRV record command line wrapper

wrapsrv adds support for connecting to a network service based on DNS SRV record lookups to commands that
       do  not  support the DNS SRV record. wrapsrv implements the weighted priority client connection algorithm
       in RFC 2782. The specified command line will be invoked one or more times with %h and %p sequences in the
       command line substituted for the hostname and port elements of the selected SRV record. The command  line
       invoked  must  exit and return 0 after a successful connection or exit and return non-zero if the connec‐
       tion fails. wrapsrv will itself exit with the return code of the last command line invocation, or it  may
       exit with a non-zero return code if the DNS SRV record lookup fails for any reason.
