[racket] raco commands via planet

  I tried adding a command to raco in the info.rkt file of my planet 
package but I can't find the correct module path to use. If I try a 
local path then raco dies with "cannot find blah.rkt", if I try a path 
like (planet me:package/1/0/blah) then `module-path?' returns #f and 
raco dies (line 20 of raco/all-tools.rkt).

(define raco-commands '(["extract" (planet kazzmir:check/1/0/check)
                          "show module information" 50]))

Or

(define raco-commands '(["extract" "check.rkt"
                          "show module information" 50]))
