Pre/Post Scripts and CMDline Parameters for Uninstall
For the install process there is the very useful functionality to have pre and post script, add files and folders and define some additional Cmdline Arguments. We need the same options for uninstall process.
Sometime we made some special reg-keys or copy some special content during the install process by using post script. When the user uninstall the sw by software center the customizing from the post scripts still exists.
