This directive inserts a “TOC tree” at the current location, using the individual TOCs (including “sub-TOC trees”) of the documents given in the directive body.

Relative document names (not beginning with a slash) are relative to the document the directive occurs in, absolute names are relative to the source directory.

A numeric maxdepth option may be given to indicate the depth of the tree; by default, all levels are included
