code: def remove_bcbiopath():
      
      to_remove = os.environ.get("BCBIOPATH", utils.get_bcbio_bin()) + ":"
      if os.environ["PATH"].startswith(to_remove):
          os.environ["PATH"] = os.environ["PATH"][len(to_remove):]
docs: Remove bcbio internal path from first element in PATH.
  
      Useful when we need to access remote programs, like Java 7 for older
      installations.
