Confused about describe (Was: Re: [Maxima] Re: sin, cos into exponentials)

So now that I know about exponentialize, I wanted to read its
documentation.  This resulted in major confusion about what describe
actually does:

,----
| (C1) describe(exponentialize);
| 
| 
| 
| Info from file /usr/share/info/maxima.info:
|  - Variable: FALSE
|      - the Boolean constant, false. (NIL in LISP)
| 
| (D1) 				     FALSE
`----

This does not seem to describe the function, does it?
But the function is there:

,----
| (C2) exponentialize(sin(x));
| 
| 				   %I x	    - %I x
| 			     %I (%E     - %E	  )
| (D2) 			   - ----------------------
| 				       2
`----

Looking for substrings:

,----
| (C5) describe(expon);
| 
| 
|  0: DOT0NSCSIMP :(maxima.info)Definitions for Matrices and Linear Algebra.
|  1: DOT0SIMP :Definitions for Matrices and Linear Algebra.
| Enter n, all, none, or multiple choices eg 1 3 : all
| 
| Info from file /usr/share/info/maxima.info:
|  - Variable: DOT0NSCSIMP
|      default: [TRUE] Causes a non-commutative product of zero and a
|      nonscalar term to be simplified to a commutative product.
| 
| 
|  - Variable: DOT0SIMP
|      default: [TRUE] Causes a non-commutative product of zero and a
|      scalar term to be simplified to a commutative product.
| 
| (D5) 				     FALSE
`----

Neither of the DOT0*SIMP seems to mention anything containing "expon",
whereas looking for "exp" finds "exponentialize" but none of the
DOT0*SIMP variables.
