"""
This auto-generates the mdBook SUMMARY.md file based on the layout on the filesystem.
This generates the `src` directory based on the contents of the `text` directory.
Most RFCs should be kept to a single chapter. However, in some rare cases it
may be necessary to spread across multiple pages. In that case, place them in
a subdirectory with the same name as the RFC. For example:
0123-my-awesome-feature.md
0123-my-awesome-feature/extra-material.md
It is recommended that if you have static content like images that you use a similar layout:
0123-my-awesome-feature.md
0123-my-awesome-feature/diagram.svg
The chapters are presented in sorted-order.
