col-vector * row-vector = matrix, how ?

Need to know how to accomplish the following in Mathematica-3.0:

v1 := transpose(<a,b,c>)   /* column-vector */

v2 := <x,y,z>              /* row-vector */

( ax ay az )
( bx by bz ) = v1 * v2 =: m /* 3x3-matrix */
( cx cy cz )

Does anyone know how to do this in Mathematica ?

Any help is highly appreciated.
Thanks in advance.

Malte.
