# Find and delete all symlinks to the dotfiles defined in $BRIEFCASE.
#
# Oftentimes I corrupt the state of my dotfiles. The intention with this script
# is to write some tooling to help me better manage my dotfile cleanliness. An
# example workflow might look like:
#
# ```shell
# > ./delete_dotfile_symlinks.py --audit
# > ./delete_dotfile_symlinks.py --seriously
# > cd ..
# > make install
# ```
