### MAIN
## symlink this directory to home folder
link_dotfiles_dir

## symlink the 'Application Support' folder without a space, so I can offer a valid path in dotsyncrc
## dotsync interprets any space in a destination path - even if escaped - as a delineator for a separate destination for the same dotfile.
symlink "$HOME/Library/Application Support/" "$HOME/.ApplicationSupport" 

## sync dotfiles
~/.dotfiles/dotsync/bin/dotsync -L
