"""
This script will convert .json guideline to .rst guideline.
Only schema 2.0 is supported
1. It is possible to convert single file with --file option.
This option takes filename (not file path) as argument.
(File has to be located either in add-ons interop/add-ons/guidelines
directory or interop/guidelines directory)
2. It is possible to convert core guidelines + add-ons guidelines into
single file with --all option.
This option takes date of guideline release as argument.
3. It is possible to specify output directory with --outdir option.
This option takes path to output directory as argument.
If this option isn't used file will be stored in interop/doc/source/guidelines
Examples:
[Generating out.2020.11.rst file to interop/doc/source/guidelines directory]
python3 jsonToRst.py --file 2020.11.json
[Generating all.2020.11.rst file to interop/doc/source/guidelines directory
(core + add-ons)]
python3 jsonToRst.py --all 2020.11
[Generating out.2020.11.rst file and out.dns.2020.11.rst file to
interop/doc/source/guidelines directory]
python3 jsonToRst.py --file 2020.11.json --file dns.2020.11.json
[Generating out.2020.11.rst file to current directory]
python3 jsonToRst.py --file 2020.11.json --outdir .
