Changes in RetroForth 6.13
--------------------------
1) Modified directory structure under source/platform (each
   platform gets a subdirectory)
2) New build script
   Now builds just the port you specify. Do a './build linux' to
   build the Linux port. Calling build without any options gives
   help
3) Began initial work on new ports
   A) Windows  \ Both of these will use SDL for
   B) BeOS     / graphical output.
4) Began coding Forth libraries (in retroforth/lib.f)
   A) Structures
   B) Linked Lists
   C) String Handling
   D) Object Orientation
   E) Other
5) New words
   ' count place $copy >r r> r@ c@ c! char+ chars
6) Bugfixes
   A) allot now properly reserves storage space at HERE instead of PAD
     1) Fixes problems with STACK: and ARRAY

Notes
--------------------------
1) Many of the library routines are adapted from IsForth


Description
--------------------------
This release adds support for counted strings, a return stack, and improvements to the debugging words. Several problematic words were fixed. The build script has recieved some changes to give a little more control over the build process. Platform-dependent is now grouped into subdirectories to help organize the code a little better.

Wishlist
