See combined output file out/combined_template.json sutible for flywheel's bids-curate.

It is built by removing any comments and combining all the rules within the template.

Importatnly, 00_template.json is named with leading 00 so it always sorted first. All other json files are expected to be rules.

The crux of the combination is this jq command.

jq -s '.[0] + {rules: .[1:]}' *.json

The Makefile documents the actual process.
