Changes for 0.2.3
   o fix (define (f) 1)-Bug
   o fix wrong parsing of a the string like "...\\"
   o no termination of schoca shell when an exception occurs
   o getenv retuns #f on unset vars
   o fix a lot of string functions (which uses string_of_datum instead od string_of_scm_string)
   o fix (load (...))
   o fix parsing of symbols (or numbers) starting with a dot (`.')
   o examples/schoca.init for slib is included 
           (install slib 3a1, 
            setenv SCHEME_LIBRARY_PATH
            run (load "schoca.init"))
   o fix cond bugs
   o fix scm_eval (evaluation of arguments)

Changes for 0.2.2:
   o much faster function calls (ack.scm 8.3s -> 5.9s)

Changes for 0.2.1 (not released)

   o Fix for eq? on numbers.
   o `truncate' added
   o documentation for ScmTypes
   o some functions are renamed

Changes for 0.2.0
   
   o Fix for call/cc. The implementation in schoca 0.1.0
     made use of a simple try/catch-block.

     Franklin Chen wrote this demo to show a general problem
     with this approach:

     (define retry #f)

     (define factorial
       (lambda (x)
          (if (= x 0)
            (call/cc (lambda (k) (set! retry k) 1))
            (* x (factorial (- x 1))))))

     (factorial 4)
     (display (retry 2))
     (newline)
   
   o apply Philippe Audebaud's patch (typos/make clean)
   o Fix typos in read_ini_file.ml (reported by Benjamin Geer)
   o you can now write schoca-Scripts like

       #!/usr/bin/schoca

      (display "Hello World!\n")
      (newline)
     
     This was suggested by Benjamin Geer.

    o fix wrong handling of EOF
    o all module names got a `Scm'-prefix 
    o ScmTypes.of_bool is added
    o `display' flushes ouput-port
