Changes in RetroForth 6.14
--------------------------
1) Added initial version of "Linux Services for RetroForth" (LSR)
2) Unfinished/untested ports and library code are now in opt
   subdirectory.
3) Added words: sp@ pick stars spaces
4) IF/THEN now work!
5) Fixed warning in build script
6) Looping (via if/then and return stack) works
7) Rewrote in Forth:
   '

Notes
--------------------------
1) The idea for sp@ and the new implementations of dup, over, drop, pick
   came from ASau (I *think* correct me if I'm wrong!)
2) IF/THEN took me two hours to get working, could be made smaller.
3) Loops can be done using IF/THEN and the return stack:
   : star  '* emit ;
   : stars star 1 - >r r@ 0 = if ;; then r> stars ;

   This code:
       1 - >r r@ 0 = if ;; then r> 
   is common to most loops. Just put what you want to do _before_ this 
   code and the name of the word at the end. Recursion is very nice :)


Description
--------------------------
RetroForth Release 6.14 is a significant release for several reasons. While some of the words are now better implemented, and a few new words (including 'pick stars spaces sp@') have been added, the biggest news is the working implementation of IF/THEN. The behaviour works for me, but if anyone has problems, I'll try to solve them. Using the return stack with if/then also provides loops.


Todo
--------------------------
TIMES/REPEAT (Loops can be done via a handy kludge)
   1 - >r r@ 0 = if ;; then r>
