installing strategy/delete problems

[Eric Chatonet]

Hello,

With OS X, apps are folders (bundle)
Use revDeleteFolder (delete folder deletes only empty folders).
Here with 10.4.1:

on mouseUp
   answer file "" -- select any duplicated app bundle
   revdeletefolder it
   put the result
end mouseUp

Works perfectly :-)

Best regards from Paris,

Eric Chatonet.
