Files should have their build and execution instructions attached.

[RobertZenz]

Each file should sport their build and execution instructions, ideally in the header as comments, maybe even required versions (for example the Java version requires Java 8).

That would allow every one to build and run every file, no matter if they are familiar with the toolchain or not. For some files, like the shell, it's as simple as executing the file, others, like the Java version, require a two step process (build and execute).
