 18.2.4.3 Booleans
 .................
 
 Here are functions and macros for operating on booleans.
 
  -- Macro: SCM SCM_BOOL_T
  -- Macro: SCM SCM_BOOL_F
      The Scheme true and false values.
 
  -- Macro: int SCM_NFALSEP (X)
      Convert the Scheme boolean value to a C boolean.  Since every
      object in Scheme except `#f' is true, this amounts to comparing X
      to `#f'; hence the name.
 
  -- Macro: SCM SCM_BOOL_NOT (X)
      Return the boolean inverse of X.  If X is not a Scheme boolean,
      the result is undefined.
