Run markdown codeblocks by its heading.
It searches(case ignored) for a cr.md file, then .cr.md, then README.md in the current or parent directories.
You can refer the markdown file to use with option -f or --file.
For more information, run with option --help.
For example:
./cr test sh -- foo barFeatures:

- MD_EXE
- MD_FILE

The basic idea is make markdown work like makemenuconfig
Test with README.md
- find the target markdown file in current dir in the name of README.md case ignored, if not found, search upper dir, or direct a file with -f or --file option
- run Tag as subcommand, following arguments as positional arguments.
- depends
- target toolchain
