H[elp] [option_name]

Optional. Displays a list of options and their associated arguments unless the 
option_name argument is specified. 

If you specify an option_name argument, DTUtil displays the command line help
for the specified option.

For example, the following is used to display the extended help for the Quiet 
option:

DTUtil /Help Quiet
 or
DTUtil /H Q


DTUtil supports performing one of several actions against a source package.
The source package and its location are specified with the /SQL, /FILE, and 
/DTS commands.  Some actions require a destination package and its location.

For example the following copies the srcPackage, which is on a local SQLServer,
to destPackage, which will be on the local SSIS Store.

DTUtil /SQL srcPackage /COPY DTS;destPackage 

NOTE: Commands can be in any order.  Therefore, the above example could be 
written as:
DTUtil /COPY DTS;destPackage /SQL srcPackage
