[Scons-users] Reading a file in an emitter

[William Roberts]

I have solved the issue, and it was in the documentation for the scanner.
However, a scanner is not what I think is needed.
I am looking at the scanner, and it appears to be for dependencies, not for
modifying the targets that get built, is that correct?

I tooke the file path that I was trying to open and created a Node.File()
object and used get_contents() method to retrieve the data

Thanks.
