 # forth.jl
 
 A hobby implementation of a FORTH-like system atop the Julia scientific
-computing language.  It will never be useful for any purpose besides, perhaps,
-pedagogical - although I wouldn't advise trying to learn forth by using this
-code directly. A better approach is to combine reading something like Leo Brodie's
-book Starting Forth with implementing your own forth.
-
-To a large degree this project is simply a port of the literate programming
-project JonesForth from x86 assembly + forth to julia + forth, although the
-mapping is in a few places non-trivial due to the fact that julia is a high
-level language.  A huge proportion (say 80%) of the library code in src/lib.4th
-is directly copied from JonesForth.  I've added some additional core definitions
-and modified some of the others to be a little bit closer to the behaviour of
-ANS forth (or at least FORTH 83).

 There's quite a lot to say about the implementation, especially due to its
 high-level grounding, but that will have to wait for another time.

 There's an example Mandelbrot Set drawing program included in the examples
