Tutorial:Packaging de WebApps

List and comparison of various webapps packaging, with the aim at finding commonalities and differencies to create a directory structure compatible with a largest set of deployment targets. (Possibly if there are uncompatible directory structures between two deployment targets, it will be up to the developer to choose what target s/he prefers.)
