Is there anybody who used FireBird DB?

[Suliman via Digitalmars-d-learn]

For my regret I need way to work with FireBird. I have found only 
one driver for D https://github.com/jiorhub/fired

Before I did not work with C-bindigs and D. So I can't understand 
how to use this files.

Could anybody help and explain how to work with it?
