Be aware that most of what is in scripts is being (slowly) ported into my z stateful command tree monolith utility. I'm even going to bundle my .vimrc and .bashrc files as embedded so I can setup my environment with a single command, anywhere.
For questions about design decisions and setup consider my zet notes.
