This was originally a standalone set of scripts I collected in the bin directory, mostly for automating the creation of personal Spark clusters via AWS EMR for exploratory analysis using spark-shell. Sometime after that, I stopped having that particular need, but wound up bootstrapping a couple of different machines for development, and so I filled out some generic dotfiles that I use, both true dotfiles and moduler bash profile includes.
Probably don't actually pull this repo down unless you're me, and certainly don't run setup unless you want your bash profile overwritten.
