diffutils: Bugs

 
 18.2 Reporting Bugs
 ===================
 
 If you think you have found a bug in GNU 'cmp', 'diff', 'diff3', or
 'sdiff', please report it by electronic mail to the GNU utilities bug
 report mailing list (http://mail.gnu.org/mailman/listinfo/bug-diffutils)
 <bug-diffutils@gnu.org>.  Please send bug reports for GNU 'patch' to
 <bug-patch@gnu.org>.  Send as precise a description of the problem as
 you can, including the output of the '--version' option and sample input
 files that produce the bug, if applicable.  If you have a nontrivial fix
 for the bug, please send it as well.  If you have a patch, please send
 it too.  It may simplify the maintainer's job if the patch is relative
 to a recent test release, which you can find in the directory
 <ftp://alpha.gnu.org/gnu/diffutils/>.
