Résumé : This document briefly describes FrameLib, a C++ library to manipulate "frames" as they are used in the Artificial Intelligence world. The library provides a general framework (!) for creating new frames (!!) by inheritance. The intended use is to generate new frames automatically, from a frame description language. But nothing prevents from using this library "manually". This document should be sufficient for directly using the library or for using it on an automatic generation basis. It also presents some design issues for those who are interested in the guts of the library. Note that FrameLib requires a C++ compiler supporting templates, ANSI exceptions, and RTTI (Run Time Type Information)
