# If the dotfile exists in the dotfile directory then delete dotfile from original source and replace with a symlink pointing to the specified dotfile in the ~/dotfile dir

# Adding a new dotfile:
# 1. Make a copy of the dotfile to the ~/dotfiles dir
# 2. Add a corresponding variable containing the path to the dotfile in the Paths for dotfiles section
# 3. Add a variable for the symlink location in the Symlink targets section
# 4. Add a call to the Function calls section - Call the create_symlink_to_dotfile function supplying the symlink location and dotfile location as arguments in that order
