WPKG will do this automatically but only if you define appropriate checks.

For example if you assign a package for ImgBurn to the clients where 
ImgBurn is already installed (but WPKG never run before) then WPKG will 
first run the checks. So if you define an 'uninstall' type check for 
"ImgBurn" then WPKG will claim that ImgBurn is already installed, add it 
to wpkg.xml and it will not run any installer/upgrade command.

So this is exactly what you might need.

Please note that this only works with appropriate checks so WPKG can 
detect that a package is already installed. Packages with no checks, 
inappropriate checks (evaluate false) or execute=always attribute will 
be installed.


So in best case all your packages have appropriate checks and WPKG will 
simply fill wpkg.xml without installing anything - and therefore monitor 
for updates in the future (or allow uninstall of course).
