Libical — an implementation of iCalendar protocols and data formats
Most of the code in here was written by Eric Busboom with help from dozens of contributors. It is currently maintained by Art Cancro and Wilfried Goesgens.
Libical is an Open Source implementation of the iCalendar protocols and protocol data units. The iCalendar specification describes how calendar clients can communicate with calendar servers so users can store their calendar data and arrange meetings with other users.

This dual license ensures that the library can be incorporated into both proprietary code and GPL'd programs, and will benefit from improvements made by programmers in both realms. I will only accept changes into my version of the library if they are similarly dual-licensed.
