Drupal Content Type Module Skeleton

If you're a big fan of CCK, you've probably noticed that there are limitations eventually. It does fantastic work with data, but not so much with the nodes themselves. If you need things like access rights, redirection after XYZ, or custom permissions for business logic, you will like end up having to create your own content type through a module. Following is a very simple copy paste you can use to get started. It's got the most common hooks in there. Just copy and replace 'node_type' with whatever you wish yours to be. I'll include a .info, .install, and .module to make things extra cheesy.

node_type.info

name = Content Type
description = Description
package = Custom
version = VERSION
core = 6.x
