+scheme.forth.jl
+---------------
+
+A hobby scheme implementation for FORTH 83. Specifically it is targeted at my
+own [forth.jl](http://github.com/tgvaughan/forth.jl) which is an implementation
+of FORTH on top of [Julia](http://www.julialang.org), hence the name.  However
+it does not rely on anything but standard FORTH 83 words.
