Package request: Wt
C library for developing web applications.
The API is widget-centric and uses well-tested patterns of desktop GUI development tailored to the web. To the developer, it offers abstraction of many web-specific implementation details, including client-server protocols (HTTP, Ajax, WebSockets), and frees the developer from tedious JavaScript manipulations of HTML and dealing with cross-browser issues.
