 #   Paths from Index: lines are used rather than the paths on the patch lines, which
 #       makes patches generated by "cvs diff" work (increasingly unimportant since we
 #       use Subversion now).
 #   ChangeLog patches use --fuzz=3 to prevent rejects, and the entry date is reset in
 #       the patch before it is applied (svn-apply sets it when applying a patch).
 #   Handles binary files (requires patches made by svn-create-patch).
 #   Handles copied and moved files (requires patches made by svn-create-patch).
 #   Handles git-diff patches (without binary changes) created at the top-level directory
