fcitx-frontend-qt5 binary package in Ubuntu Trusty amd64

 Fcitx is the Free Chinese Input Toy of X, which was initially designed
 for Chinese users, and used XIM protocol. Now it has already evolved
 into a highly modularized, feature rich input method framework for
 Unix-like platforms supporting a considerable amount of frontends,
 backends and modules.
 .
 It offers a pleasant and modern experience, with intuitive graphical
 configuration tools and customizable skins and mapping tables.
 It is highly modularized and extensible,
 with GTK+ 2/3 and Qt 4/5 IM Modules, support for UIs based on Fbterm,
 pure Xlib, GTK+, or KDE, and a developer-friendly API.
 .
 This package provides the Qt5 IM Module frontend, which is necessary
 for Fcitx users who would like to use Qt5 applications.
