KDE is the largest Free and Open Source community writing Qt software. Its large portfolio of applications for a wide spectrum of domains has lead to an equally wide spread spectrum of libraries for general functionality, platform integration and domain specific tasks. Qt application developers are often not aware of what is available or are uncertain what dependencies an interesting library might have. This talk will introduce two KDE initiatives to address those needs: Inqlude, a repository for Qt libraries, and KDE Frameworks 5, a reorganization of KDE's libraries into a modular structure with fewer, cleaner and better documented dependencies.
