Frob-* utilities

[Zaki, Ahmed]

Hi,

I am new to P11kit and I am trying to learn about the different utilties/tools available. 

I came across the trust directory and I read the documentation regarding the trust module but I still can’t understand how some from-* utilities work and whether these are test files ? How would they be invoked ?

Not all of them have usage information in the code, hence why I decided to ask here if I am missing how to run them correctly ?

I am specifically talking about 

Trust/frob-bc
Trust/frob-cert
Trust/frob-eku
Trust/frob-ext
Trust/frob-oid
…

Thanks
