Parser2 is an alternative implementation of Gerber AST parser redesigned to make process
of implementation of Gerber features easier and quicker in addition to much better
extension interface. Moreover it provides a easy way to introspect Gerber code with use
of hook based interface.
!!! tip "Contributing"
Community contributions are always welcome, they can speed up process of migrating
from Parser to Parser2.
