LibGC is a garbage-collection library for C++. The most important features of the library are:

• portability; the library is easily portable because it uses standard C++.
• threads support. Optionally single-threaded.
• easy to use: it has only two classes.
• fast.
• precise; it is only pointers that are scanned.

LibGC uses the mark and sweep algorithm: when there is not enough memory, live objects are marked, and unreachable objects are deleted. A smart allocation algorithm ensures fast allocation of objects. The memory is not defragmented during a collection (due to the difficulty of that), but the allocation algorithm makes sure memory is sufficiently re-used.
