# Nasal
|
|
|
|
Nasal is a script language that used in FlightGear.
|
|
|
|
There is a Nasal console in FlightGear but sometimes it is not so easy for every developer to use.
|
|
|
|
So this is an interpreter for Nasal written by C++.
|
|
|
|
The interpreter is still in development.Anyone who interested in this could also join us!
