generate.section.toc.level — Control depth of TOC generation in sections
controls the depth of
section in which TOCs will be generated. Note
that this is related to, but not the same as
toc.section.depth, which controls the depth to
which TOC entries will be generated in a given TOC.
If, for example,
3, TOCs will be generated in first, second, and third
level sections, but not in fourth level sections.
