# WARNING:
# This file is use by all OpenStack-Ansible roles for testing purposes.
# Any changes here will affect all OpenStack-Ansible role repositories
# with immediate effect.

# PURPOSE:
# This script executes bashate against all the files it find that match
# the search pattern. The search pattern is meant to find any shell
# scripts present in the role.
#
# The test ignores the following rules:
#
# E003: Indent not multiple of 4 (we prefer to use multiples of 2)
#
# E006: Line longer than 79 columns (as many scripts use jinja
#       templating, this is very difficult)
#
# E040: Syntax error determined using `bash -n` (as many scripts
#       use jinja templating, this will often fail and the syntax
#       error will be discovered in execution anyway)
