Problem Activating a Feature Using STSADM

Hi

I created a timer job for SP-2010.  When I add the solution SharePoint creates the following:

"14\TEMPLATE\FEATURES\GWR.Legal_InventoryJobFeature\feature.xml"

I try running the following stsadm command from the "features" directory:

stsadm -o activatefeature -filename GWR.legal_inventoryjobfeature\feature.xml -name gwr.legal_inventoryjobfeature -id d2f1.... -url http://gw-lab

It gives me the following error:

Please use one of the -filename, -name, or -id arguments to select a feature

I'm not sure what's going on, because I am using these arguments.  Any help is appreciated.
