The help/messages in other languages should be removed, can start just with English. (They are still referring to simple example anyway.)

The help files still need to be trimmed

[thc202]

It seems the help is still from the example add-on. There's also code that's from the example that should be removed.

I am uncertain as to how exactly the helpfiles work. there still are some target references to "simple". do these need to be changed too? if yes can i just rename the target or do i need to define the target somewhere first?

[thc202]

Yes, it should use its own custom "prefix", where's simple it should be e.g. sqlmap.
