python-docs-fr/Makefile

# 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 verifs  # To check for correctness: wrapping, spelling
# - make wrap  # To check for wrapping
# - make spell  # To check for spelling
# - make merge  # To merge pot from upstream
# - make fuzzy  # To find fuzzy strings
# - make progress  # To compute current progression
#
# 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.

# Configuration

# The CPYTHON_CURRENT_COMMIT is the commit, in the cpython repository,
# from which we generated our po files.  We use it here so when we
# test build, we're building with the .rst files that generated our
# .po files.
