# Runs the "test-python.sh" test, setting proper environment variables
# for the build tree.
#
# - the first three arguments are the BUILDDIR, SRCDIR and PYTHON paths.
#   The following arguments are passed on to "test-python.sh".
#
# - you can use "--" to separate the extra arguments.
#
# The full format is
#
#   $ src/tests/client/test-client.sh "$BUILDDIR" "$SRCDIR" "$PYTHON" -- "${EXTRA[@]}"
#
# - "$BUILDDIR" "$SRCDIR" and "$PYTHON" can be set to "", to fallback
#   to a default.
#
# The safe way to call it is thus
#
#     $ src/tests/client/test-client.sh "" "" "" -- "${EXTRA[@]}"
#
# but for brevity, you can also call
#
#     $ src/tests/client/test-client.sh -- "${EXTRA[@]}"
#
# if (and only if) "${EXTRA[@]}" does not contain "--".
