Hello Rohin,
GNU diff has the option -I RE (i.e., ignore regular expression), but I don't
know if your version of cvs diff will pass through your option.
You might have to resort to
cvs update -r <version1> -p filename > filename~<version1>~
cvs update -r <version2> -p filename > filename~<version2>~
diff -I '^ *//' filename~{<version1>,<version2>}~
But that regexp handles only C++ comments. I don't know of a way to
recognize /* ... [text containing newlines] ... */. Possibly another
diff utility has that options (xxdiff, tkdiff?).
