-PURPOSE: Provide generally useful macros and functions for MetaLanguage
-         and Boot code.  Contents are organized along Common Lisp datatype
-         lines, with sections numbered to match the section headings of the
-         Common Lisp Reference Manual, by Guy Steele, Digital Press, 1984,
-         Digital Press Order Number EY-00031-DP.  This way you can
-         look up the corresponding section in the manual and see if
-         there isn't a cleaner and non-VM-specific way of doing things.

-\section{Performance change}
-
-Camm has identified a performace problem during compiles. There is
-a loop that continually adds one element to a vector. This causes
-the vector to get extended by 1 and copied. These patches fix the 
-problem since vectors with fill pointers don't need to be copied.
-
-These cut out the lion's share of the gc problem
-on this compile.  30min {\tt ->} 7 min on my box.  There is still some gc
-churning in cons pages due to many calls to 'list' with small n.  One
-can likely improve things further with an appropriate (declare
-(:dynamic-extent ...)) in the right place -- gcl will allocate such
-lists on the C stack (very fast).

-\subsection{lengthenvec}

-The original code was:
-\begin{verbatim}
-(defun lengthenvec (v n)
-  (if (adjustable-array-p v) (adjust-array v n)
-    (replace (make-array n) v)))
-\end{verbatim}
-
-<<lengthenvec>>=
-(defun lengthenvec (v n)
-  (if 
-    (and (array-has-fill-pointer-p v) (adjustable-array-p v))
-    (if 
-      (>= n (array-total-size v)) 
-        (adjust-array v (* n 2) :fill-pointer n) 
-        (progn 
-          (setf (fill-pointer v) n) 
-          v))
-    (replace (make-array n :fill-pointer t) v)))

-\subsection{make-init-vector}

-\begin{verbatim}
-(defun make-init-vector (n val) (make-array n :initial-element val))

-\section{DEFUN CONTAINED}
-
-The [[CONTAINED]] predicate is used to walk internal structures
-such as modemaps to see if the $X$ object occurs within $Y$. One
-particular use is in a function called [[isPartialMode]] (see
-i-funsel.boot) to decide
-if a modemap is only partially complete. If this is true then the 
-modemap will contain the constant [[$EmptyMode]]. So the call 
-ends up being [[CONTAINED |$EmptyMode| Y]]. 
-<<DEFUN CONTAINED>>=
-#-:CCL
-(DEFUN CONTAINED (X Y)
-  (if (symbolp x)
-      (contained\,eq X Y)
-      (contained\,equal X Y)))
- 
-(defun contained\,eq (x y)
-       (if (atom y) (eq x y)
-           (or (contained\,eq x (car y)) (contained\,eq x (cdr y)))))
- 
-(defun contained\,equal (x y)
-   (cond ((atom y) (equal x y))
-         ((equal x y) 't)
-         ('t (or (contained\,equal x (car y)) (contained\,equal x (cdr y))))))
