Jacob is a stand-alone Oberon-2 compiler. It compiles a single Oberon-2 module together with its imported modules and links everything together to form an executable. It implements the full Oberon-2 language specifications. External modules allow developers to write library modules in other languages. Instead of an explicit dispose function a garbage collector is implemented using the mark-and-sweep algorithm. There are command line options for enabling and disabling NIL, index, range, and assertion checks.
