OurBigBook stores some metadata and outputs it generates/needs inside the ./out/ directory that it creates inside the --outdir <outdir>.
Overview of files it contains:
  • db.sqlite3: cross file reference internals
  • publish: a git clone of the source of the main repository to ensure that untracked files won't accidentally go into the output
    • publish/out/db.sqlite3: like out/db.sqlite3 but from the clean clone of out/publish
    • publish/out/publish: the final generated output directory that gets published, e.g. as in publish to GitHub Pages
