dtl – Tools to dis-as­sem­ble and re-as­sem­ble DVI files

DTL (DVI Text Lan­guage) is a means of ex­press­ing the con­tent of a DVI file, which is read­ily read­able by hu­mans. The DTL bun­dle con­tains an as­sem­bler dt2dv (which pro­duces DVI files from DTL files) and a dis­as­sem­bler dv2dt (which pro­duces DTL files from DVI files).
The DTL bun­dle was de­vel­oped so as to avoid some in­fe­lic­i­ties of dvi­type (among other press­ing rea­sons).
