I may be obtuse, but short of writing a module how can I set a cfengine

it done before, but I can't find it.
I want to do set a variable (call it $(my_ypserver)) to the output of the
/usr/bin/ypwhich command. A module seems like overkill for this....
I have a lot of lines like this:
FailoverKey = ( ExecResult(/bin/cat
/var/cfengine/inputs/keys/failover.pubkey) )
Seems to work fine, though I bet there's a more efficient way of doing it.
