* https://gobyexample.com/directories
* https://blog.kowalczyk.info/article/wOYk/advanced-command-execution-in-go-with-osexec.html
* https://golang.org/pkg/os/
* Remove the default files in /etc/skel and replace with ones from dotfiles/config
* Sync the vim plugins directory
* Create symlinks for useful directories if they exist - gdrive, documents, etc
* Sync git repositories
* Define and build go modules (then create a separate go module to rebuild them)
