Request for additional Pre-defined Descriptors

Hello, I love Maven and all of it's wonderful plug-ins like this one. However, I think that the amount of configuration to do very common and simple things, while flexible, is getting a bit out of hand in my honest opinion. I'd like to see the assembly plugin have more pre-defined descriptors for certain things. By doing so, I think it would help folks use the assembly plugin to create artifacts easier without making mistakes which require a great deal of time to resolve, as well as help with productivity since you wouldn't have to troll through a lot of documentation, and web resources, to do something which should be very simple to setup.

Therefore, if you would be so kind , I would like to see a pre-defined descriptor for a jar in the format expected by a Hadoop for a Map Reduce application. According to the book "Hadoop The Definitive Guide" by Tom White, the jar should be structured as such:

Chapter 5:
"Also, any dependent JAR files should be packaged
in a lib subdirectory in the JAR file. (This is analogous to a Java Web application
archive, or WAR file, except in that case the JAR files go in a WEB-INF/lib subdirectory
in the WAR file.)"

It's a simple descriptor, which I have attached, but it would be a start to help build out the pool of pre-defined descriptors to make it easier, and more efficient, to create/manage maven projects.
