Advanced HTML TOC creates a table of contents (TOC) of HTML files from header tags. It can process single or multiple files. Automatically uses existing named anchors inside header tags or creates new ones if none. Automatically links TOC items to header tags. User sets range of header tags being used in TOC. This can be used to create TOCs of various depths from the same files. Can process page titles, which is useful for multiple file processing. Titles have precedence over H1 tag. Completely re-entrant. Can put numbering (like "1.20.4.") both into TOC items and header tags. TOC appearance is based on a template. User specifies a place where to insert TOC. IF place is not specified, program selects a place automatically.
