Variable assignments from shell commands

According to section 8.11 of the gnu manual, I should be able to use the shell command to assign a variable.  However, this doesn't work.  

I've tried assigning the variable from outside a rule but the command does not get executed and the variable is empty.  The only time the shell command is executed is from within a rule but variable assignments within rule is not allowed.

     contents := $(shell cat foo)

Any thoughts?
