looking for cvs utility to annotate which checkin each line came from

[jonathan cano]

I'm looking for a utility that prints out a CVS controlled file with
each line prepended with the version that the line was checked in
under.  E.g.

  % cvs_cat_versions   foo.c

    1.1      : /*
    1.1      :  * blah
    1.1      :  */
    1.1      : #include <stdio.h>
    1.1      :
    1.1      : typedef struct {
    1.3      :     int a;
    1.22     :     int b;
    1.1      :     char buf[7];
    1.1      :
    1.1      : } a_t;
    1.1      :
    1.41     : typedef struct {
    1.41     :     char buf[50];
    1.41.2.1 :     short       s1;
    1.41     : } b_t;
    1.1      :

does such a utility already exist?  I've googled but to no avail.  If
'cvs_cat_versions' does exist I don't know what search words I need to
find it.
