libxmlrpcpp1d 1.13.5+ds1-3 (amd64 binary) in ubuntu bionic

 This package is part of Robot OS (ROS). It contains the XmlRpc++
 library, which is a C++ implementation of the XML-RPC protocol. This
 version is heavily modified from the package available on SourceForge
 in order to support roscpp's threading model. As such, it's a
 maintained fork by OSRF.
