The last three modules — the document model, the Markdown renderer, and the
formula renderer — were the largest, and every file with comments now
carries them in English and then in Chinese, as the library does. Three
thousand eight hundred and seventy comment lines across forty-three files.
The audit that renders every route is now part of the project rather than a
script kept outside it, because a release needs it and the next person
should not have to write it again. It is documented in the README beside
the other script.
Two faults of my own were found and fixed while writing the comments. A
blank line between two doc comment lines detaches the second block from the
item it documents; the compiler says so and it was said of ninety-three
such lines, which are now empty doc lines. And a few blocks were inserted
with the wrong indentation, which then tidied.
