ltxd­iff – A Win32 pro­gram that com­pares to­kens in two .tex files

The pro­gram com­pares to­kens in two .tex files (or di­rec­to­ries, pos­si­bly with sub­di­rec­to­ries, con­tain­ing .tex files) and marks dif­fer­ences ac­cord­ing to the op­tions set, by us­ing GNU Diff to find to­kens to be marked.
Another diff pro­gram may be used as well if it has the switches -b, -B, -d, and -E and they have the same ef­fect as with GNU diff.
