The Maple package jets was developed by Mohamed Barakat and Gehrt Hartjen. Originally it was an extension of the package desolv, adding to it the facility of computing generalized symmetries. At the current stage it is an independent package going beyond symmetries to handle different aspects I. M. Gel'fand, in his 1970 address to the International Congress in Nice, called "formal differential geometry". Important parts of the variational bicomplex, as playing a crucial role in the formal theory of PDEs, are implemented in jets. Recently, the formalism of jet-groupoids found its way into jets.If you find a bug please feel free to send me an email.
