  <!-- Inputs: $(OutputPathBuild) - location of the build results
               $(OutputPathDeployment) - where the resulting ClickOnce files are to be stored
               $(Version) - application version to be used (you should **REALLY** make this the same
                            as assembly version, but that's far from trivial and outside the scope
                            of this example).
               $(Mage) - full path to the mage tool

               Assumes a certain directory structure that need not be the case
               Sets both min & max version, making all updates required
               Requires full trust.
               Application icon is expected at "Resources\Icon.ico"; a signing key at "Keys\MyApp.pfx"
               Application can be started offline
               Links are installed in the Start Menu, but no desktop shortcut is generated.
               This particular example is for x86 CPU rather than AnyCPU.

               Summary: you still have to know how to use MAGE, and have a farily good idea of what
               you want from ClickOnce. You will have to tweak a bunch of these parameters. But at
               least you have a known working example to start with. You will have to generate a pfx
               key one way or another - again, outside the scope of this example (and could certainly
               have been made less of a PITA to generate by MS.
