Initial Alpine Linux Dotfiles.
After having jumped from Arch to OpenBSD to FreeBSD, now I'm back on Linux and have chosen Alpine. I want to clean up all the cruft that has accumulated over the years. Many programs that were in my dotfiles I no longer use. So, these dotfiles are a drastically simplified view of my old dotfiles, which I have created so I can start fresh. The .profile and .ashrc are meant to be entirely POSIX, so they should work on any shell.
