Changes relative to tre-0.20:
  * CL: *ARGV* has the command-line arguments.
  * DEFSTRUCT: Generated macro DEF-name does not require the first argument
    to be of the structs name any more.
  * Inside methods package "GLOBAL" now tells that a symbol should not be
    thisified, allowing to access the symbol of the same name outside the
    class if it's being used as a method name already.
    E.g.: If you have a method named AREF and you want to access the global
    AREF function, just write 'global:aref' in the function call.
  * NEW without arguments does not create a JSON object but a standard object.
    Use MAKE-JSON-OBJECT.

       …: LIST
      *>: APPLY
      ~>: FUNCALL
      +@: MAPCAN
      @n: MAPTIMES
  * PHP classes: array accessors may be overloaded by members AREF, =-AREF and
    DELETE-AREF.  PHP requires them all to be there if used.
  * Added VECTOR?.
  * EVERY much faster on lists.
  * Added DIRECTORY to get directory lists.
  * Added DUMP to CL target.
  * Added GETENV.
  * Added standard set functions SET-DIFFERENCE,

      ATTR, ATTR? and ATTRS.

    repositories on Github will be removed.
