[jamming] How to display or access the command line "target"

[Dana Frost]

I have an action that is calling jam (not the best idea I know) and I want
to forward on 
the same "target" that was entered from the command line. Does Jam have a 
system variable that holds the original "target" from the command line call.

For example if someone runs:

> jam build

I want an action...

actions jam_again {
   jam -s setting=g build
}

Other than having a rule for each target, is there a variable that holds the
value "build" ?
