# Finder Quick Action.
#
# Symlinks the version-controlled workflow bundle from the dotfiles repo into
# ~/Library/Services so edits in the repo take effect without reinstalling,
# then flushes the Services cache so the menu item appears immediately.
#
# Usage: md2pdf-install-quickaction [--copy]
#   --copy   Install a copy instead of a symlink (use if you prefer the
#            installed action to be independent of the repo).
