  -- DESCRIPTION :
  --   A polynomial system with as many equations as unknowns is square.
  --   This procedure solves a square polynomial system p,
  --   using double, double double, or quad double arithmetic.

  -- REQUIRED :
  --   Must be called after the special cases (one single equation
  --   and a linear system) have been dealt with.

  -- ON ENTRY :

  --   deflate        if not deflate, then not deflation will be applied;
  --   append_sols    true if solutions need to be appended to input file;
  --   verbose        the verbose level.

  -- ON RETURN :
  --   p              system may be scaled or reduced.
