Help! How to add a problem from command line

[Philogag]

I only found a way to link the data to the problem in the wiki.
I found a add function on vj4.vj4.model.adaptor.problem but it seens not suitable for command line.
How can I add a problem if I have a markdown file as the problem content.
Or please tell me which function should I use in source code, I will try it by myself.

add is for adding problems. You can also write a function like add_file to add problems loading the contents from files.
