# Use the -l | --last option to generate a link based on the most
# recent page-bundle created (this does not work if the post has been
# sitting around / worked on for a bit).
#
# If no option is passed in then it will open an fzf (fuzzy search)
# from the directories.
#
# Use the --local option to generate a link to a version running on localhost.
#
# A general usage to generate a link and copy it to the clipboard:
