rfcdiff

compares two internet draft files and outputs the difference

The purpose of this program is to compare two versions of an internet-draft, and as output produce a diff in one of several formats: * side-by-side html diff * paged wdiff output in a text terminal * a text file with changebars in the left margin * a simple unified diff output It can also be used to compare ordinary (non-rfc) text files. In all cases, internet-draft headers and footers are stripped before generating the diff, to produce a cleaner diff.
