In this task, the job is to create a new empty file called "output.txt" of size 0 bytes
and an empty directory called "docs". This should be done twice: once "here", i.e. in the current working directory and once in the filesystem root.

["/", "./"] each: |dir| {
  # create '/docs', then './docs'
  Directory create: (dir ++ "docs")
  # create files /output.txt, then ./output.txt
  File open: (dir ++ "output.txt") modes: ['write] with: |f| {
    f writeln: "hello, world!"
  }  
}
