# The default target of this Makefile is...
all::

# Development
# -----------
# make V=1                      # generate files; V=1 increases verbosity
# make test [flags=...]         # run tests; flags=-x fails fast
# make test V=2                 # V=2 increases test verbosity
# make doc                      # build docs
# make flake8                   # python style checks
# make pylint [color=1]         # run pylint; color=1 colorizes output
# make pylint3k [color=1]       # run python2+3 compatibility checks
# make format file=<filename>   # run the yapf python formatter on <filename>
# make check [color=1]          # run test, doc, flake8, pylint3k, and pylint
# make check file=<filename>    # run checks on <filename>
#
# Release Prep
# ------------
# make pot      # update main translation template
# make po       # merge translations
# make mo       # generate message files
# make i18n     # all three of the above
#
# Installation
# ------------
# make prefix=<path> install
# DESTDIR is also supported.
#
# To disable distutil's replacement of "#!/usr/bin/env python" with
# the path to the build environment's python, pass USE_ENV_PYTHON=1
# when invoking make.
#
# The external commands used by this Makefile are...
