Binary package “libwt38” in ubuntu xenial

C++ library and application server for web applications [runtime]

 Wt (pronounced 'witty') is a C++ library and application server for
 developing and deploying web applications. The API is widget-centric
 and offers complete abstraction of any web-specific application details.
 .
 This package contains the Wt core library but you still need to install
 a connector, either the HTTP connector (libwthttp), the FastCGI
 connector (libwtfcgi) or the test connector (libwttest).
