Permission problem

My problem:
I wrote a working Permission plugin for pmmp and I want to release it soon! But I want to allow the user to give a player all subpermissions. For example:
If player has plugin.api he should also have plugin.api.command etc. But I have no idea how to do this :/

If u need more information please ask me

 

Why do u moved this????

 

*Facepalm* \(^_^)/

 

No! I really need help

 

I was trying too this in past, but failed \(^_^)| .

 

In PurePerms you can give a player plugin.* And u have all subperms of *. But I can't find this in PurePerms :/

 

Omg banned !!!!
