If you think you have found a bug in GNU cmp, diff,
diff3, sdiff, or patch, please report it by
electronic mail to `bug-gnu-utils@prep.ai.mit.edu'. Send as
precise a description of the problem as you can, including sample input
files that produce the bug, if applicable.
Because Larry Wall has not released a new version of patch since
mid 1988 and the GNU version of patch has been changed since
then, please send bug reports for patch by electronic mail to
both `bug-gnu-utils@prep.ai.mit.edu' and
`lwall@netlabs.com'.
