"JavaScript has npm, Ruby has Gems, Python has pip and now Shell has bpkg!
bpkg is a lightweight bash package manager. It takes care of fetching the shell scripts, installing them appropriately, setting the execution permission and more.
You can install shell scripts globally (on /usr/local/bin) or use them on a per-project basis (on ./deps/), as a lazy-man "copy and paste"."
