 Creating and Removing Files
 ===========================
 
    Sometimes when comparing two directories, a file may exist in one
 directory but not the other.  If you give `diff' the `-N' or
 `--new-file' option, or if you supply an old or new file that is named
 `/dev/null' or is empty and is dated the Epoch (1970-01-01 00:00:00
 UTC), `diff' outputs a patch that adds or deletes the contents of this
 file.  When given such a patch, `patch' normally creates a new file or
 removes the old file.  However, when conforming to POSIX ( patch
 and POSIX), `patch' does not remove the old file, but leaves it empty.
 The `-E' or `--remove-empty-files' option causes `patch' to remove
 output files that are empty after applying a patch, even if the patch
 does not appear to be one that removed the file.
 
    If the patch appears to create a file that already exists, `patch'
 asks for confirmation before applying the patch.
