7 * use and distribute based on the FreeBSD copyright. Supplied as-is,
8 * USE WITH EXTREME CAUTION.
10 * This program attempts to duplicate the source onto the destination as
11 * exactly as possible, retaining modify times, flags, perms, uid, and gid.
12 * It can duplicate devices, files (including hardlinks), softlinks,
13 * directories, and so forth. It is recursive by default! The duplication
14 * is inclusive of removal of files/directories on the destination that do
15 * not exist on the source. This program supports a per-directory exception
16 * file called .cpignore, or a user-specified exception file.
20 * - does not cross partition boundries on source
21 * - asks for confirmation on deletions unless -i0 is specified
22 * - refuses to replace a destination directory with a source file
23 * unless -s0 is specified.
24 * - terminates on error
28 * - does not copy file if mtime, flags, perms, and size match unless
31 * - copies to temporary and renames-over the original, allowing
32 * you to update live systems
34 * - copies uid, gid, mtime, perms, flags, softlinks, devices, hardlinks,
35 * and recurses through directories.
37 * - accesses a per-directory exclusion file, .cpignore, containing
38 * standard wildcarded ( ? / * style, NOT regex) exclusions.
40 * - tries to play permissions and flags smart in regards to overwriting
41 * schg files and doing related stuff.
43 * - Can do MD5 consistancy checks
45 * - Is able to do incremental mirroring/backups via hardlinks from
46 * the 'previous' version (supplied with -H path).
48 * $DragonFly: src/bin/cpdup/cpdup.c,v 1.25 2008/04/16 17:38:19 dillon Exp $
52 * Example: cc -O cpdup.c -o cpdup -lmd
54 * ".MD5.CHECKSUMS" contains md5 checksumms for the current directory.
55 * This file is stored on the source.
