Overview

This class is used to generate .strdef file from .md files. .strdef file is used to define the structure of the log. https://techlife.cookpad.com/entry/2019/10/18/090000 Since the .strdef generation for Redshift Spectrum is for Cookpad's internal reasons, we initially decided it would be more natural not to include it in the core of daifuku, but we added it as a reference implementation.
