I have two latex source files, one created by me and the other modified by a colleague.
Introduced modifications, unfortunately, also regard line breaks and spacing (source text line breaks, not latex ones), so that it is difficult for me to compare the files with standard unix text tools.
So I wonder if there is some latex text processor that could reduce both files to a common form, where could be simpler to spot the essential differences and hide/normalize the inessential ones. A sort of beautifier, like
tidy for html.
Alternatively, I would ear some advices on how others approach such problem.
