# TODO:
#
# - support matching multiple extensions
#
# maybe:
#
# - use fzf if called from an interactive terminal (?)
#   - what about scripts called from the commandline, but that should
#     display stuff?  probably they don't exist?
# - allow multiple directories to be searched
# - make "chooser" configurable (e.g. allow regular dmenu)
