# Create a CSV file listing the information about our 3rd party dependencies
# that is required for the stack-wide list.
#
# Usage:
# dependency_report.sh --csv <output_file>
#
# The format is that defined in https://github.com/elastic/release-manager/issues/207,
# i.e. a CSV file with the following fields:
#
# name,version,revision,url,license,copyright
#
# The way this script works, each component must have its own CSV file with
# those fields, and this script simply combines them into a single CSV file.
# Because of this, the field order is important - in each per-component CSV
# file the fields must be in the order shown above.
