Ivf++ (Interactive Visualization Framework) is a simple OpenGL/GLUT-based C++ visualization framework. Its main goal is to create a foundation of classes that can be extended in simple ways. It also encapsulates the GLUT event model in a set of easy-to-use classes (based on the GlutMaster classes), so a simple GUI can be built quickly. It can be used together with other GUI libraries using provided widgets.
libservices is a simple library to access and edit /etc/services. While editing, it allows you to add, remove, and change services preserving existent file proprieties (comments, blank lines, etc). While accessing information, it allows you to access usual information and comments. A command line utility is also provided, making /etc/services easily accessible through shell scripts. It's mainly useful for configurators and package pre/post installation scripts.
WildCAT is a Java toolkit and framework which can be used to build context-aware applications. From the client application's point of view, it provides a simple and dynamic data-model to represent the execution context of the application (for example, software and hardware resources), and offers a simple API for the programmers to access this information both synchronously and asynchronously (pull and push). Internally, it is a framework to integrate multiple sources of structured or unstructured monitoring data in a common data model.
