# FIXME making a symlink is just an workaround since smartypants script isn't
# importable, therefore Sphinx autodoc cannot pick it up. There are a couple of
# options:
#
# 1. making a `main()` function in smartypants.py, the module file. However,
#    you can't use section heading inside the docstring of a function, or it
#    would result an error about unexpected section heading.
#
#	2. making a smartypants.py as a package, so a new module like
#	   smartypants.cli, just for the command-line script
#
# If you know a better solution for making documentation for smartypants
# command, please open an issue to discuss. Right now, stick with this ugly
# symlink.
