dvi­type – Type out the con­tent of a DVI file

This is one of Knuth's orig­i­nal tools; it pro­vides a hu­man-read­able list­ing of the con­tent of a DVI file.
The web source of DVI­type also serves as a ref­er­ence for the for­mat of DVI files them­selves.
Dvi­type is part of Knuth’s texware dis­tri­bu­tion.
