Uhh, other useful third party stuff I guess
Config files for each shell individually, all bourne shells, and all shells in general. Also contains an amend directory for making amendments to the originals so you can use a custom-config on certain servers.
For the tools, like tmux, vim, etc.
It's on the PATH. For my own included-in-this-repo executables or whatever
More details in the shell folder.
