libfilezilla is a free, open source C++ library, offering some basic
functionality to build high-performing, platform-independent programs.
Some of the highlights include:

* A typesafe, multi-threaded event system that's very simple to use
  yet extremely efficient
* Timers for periodic events
* A datetime class that not only tracks timestamp but also their
  accuracy, which simplifies dealing with timestamps originating from
  different sources
* Simple process handling for spawning child processes with redirected
  I/O
