    Dotfiles are files or directories on *nix systems which filesystem
    utilities do not display by default when showing a directory
    listing.

    To list these files, run: ls -a

    On cosmic.voyage there are several dotfiles that you may want to
    customize

    1. ~/.plan & ~/.project

    These files are displayed when someone checks your account with the
    `finger` command. Create these files with the editor of your choice
    inside your HOME directory. The .plan file should contain a few
    lines with general information about you or your account. The
    .project file should only contain one line, generally contains
    information about your short-term goals. You can create either or
    both of these files, if both exist the .project file should be
    output above the .plan file when somebody runs `finger username@cosmic.voyage`

    2. ~/ship/ship_name/.description

    This file provides a description for your ship/colony/output where
    you can introduce your story or provide more information as you see
    fit.

    3. .profile / .bashrc

    These files change the way your shell runs, you can change your
    default text editor by adding a line like:

    	export EDITOR=vim

    to change your default text editor from jed to vim, or you can
    create aliases as shortcuts to your favorite commands with lines
    like:

    	alias ll='ls -oFhA'

    this one will list the contents of a directory, append a character
    to indicate the files type, and print the file size in a
    human-readable format. There's tons of options that can be tweaked
    in here.

    4. other config files

    .muttrc & .pinerc files can be written to customize the mutt and
    alpine email clients respectively.

    .signature file will be used by some email apps to be appended as a
    signature on outgoing messages.

    .vim & .vimrc is a directory of configurations and a single
    configuration file to customize the way the vim text editor works.
