# Makefile for French Python Documentation
#
# Here is what you can do:
#
# - make  # Automatically build an html local version
# - make todo  # To list remaining tasks
# - make merge  # To merge pot from upstream
# - make fuzzy  # To find fuzzy strings
# - make progress  # To compute current progression
# - make upgrade_venv  # To upgrade the venv that compiles the doc
#
# Modes are: autobuild-stable, autobuild-dev, and autobuild-html,
# documented in gen/src/3.6/Doc/Makefile as we're only delegating the
# real work to the Python Doc Makefile.
