iwdd.ipl -> iwodcmd HOW ?

System

In the OD manual section 'Migrating Notes for DataDeploy 5.6' it states that to perform command line data deploys one simply substitutes iwdd.ipl with -
iwodcmd start -k iwdd=internal-deployment-name.
Sounds easy doesn't it? But what if you were actually performing a relaistic data deployment command (rather than some useless example) that looks like this -
iwperl d:\iw-home/dd-home/bin/iwdd.ipl cfg=d:\iw-home/dd-home/bin/EmpowerStagingDDConfig.cfg deployment=document filepath=templatedata/documents/document/data/0000TESTNick.xml wa=/default/main/CriticalCare/English/Shared/WORKAREA/Home
?
What is the 'internal-deployment-name' here ??
How do I pass the od command my dd config file and all my parameters ?
I have tried something like this -
iwodcmd start -k iwdd=D:\iw-home/dd-home/bin/EmpowerStagingDDConfig.cfg deployment=document filepath=templatedata/documents/document/data
/0000TESTNick.xml wa=/default/main/CriticalCare/English/Shared/WORKAREA/Home
But all I get is -
***WARNING - Ignoring unrecognized argument: 'iwdd=D:\iw-home/dd-home/bin/EmpowerStagingDDConfig.cfg'.
***WARNING - Ignoring unrecognized argument: 'deployment=document'.
***WARNING - Ignoring unrecognized argument: 'filepath=templatedata/documents/document/data/0000TESTNick.xml'.
***WARNING - Ignoring unrecognized argument: 'wa=/default/main/CriticalCare/English/Shared/WORKAREA/Home'.
Usage: iwodcmd start -h | -v .............

Has anyone else solved this problem ?
Much thanks in advance for any help provided :-)
