hmm... I know that the default index.tcl in 3.2.4 (and 3.2.5) tries to grab stuff from the content_sections table. I don't know if it works now out-of-the-box; it didn't in 3.2.4. There is also a content_sections directory under admin. Grep for content_sections; you might also take a look at custom_sections which also references the content_sections table.
