Hello 9fans.

cpdir is updated to ver.1.4
-x option is added

#
#	Usage
#
Usage: cpdir [-vugRm]  [-l file] [-x xfile] srcdir destdir [path ...]
Options and arguments:
	-v: verbose
	-u: copy owner info
	-g: copy group info
	-R: remove redundant files and directories in dstdir
	-m: merge
	-l file:
		A file of path list to be processed.
		Path list must be a path per line.
	-x xfile
		A file of path list that should not be copied.
		Path list must be a path per line.
		Rc style globe expression is allowed for the path.
		In the matching rule, "/" is simply a character.
	srcdir:
		source dir from which copy is made.
	destdir:
		destination dir in which copy is made.
	path ... : pathes in source to be processed.

Function:
	`cpdir' makes effort to make a copy of file in srcdir
	to dstdir. Those that are copied are:
	- contents
	- modification time
	- permissions
	- group	if possible. (under -g option)
	- owner if possible. (under -u option)
	What happens if there are files of same name
	in both source and destination?
	Let s.mtime and d.mtime be modification time of source
	and destination respectively. Then `cpdir' copies:
	- contents (if s.mtime > d.mtime)
	- modification time (if source.mtime > destination.mtime)
	- permissions (if s.mtime >= d.mtime)
	- group	(under -g option, if s.mtime >= d.mtime)
	- owner if possible. (under -u option, if s.mtime >= d.mtime)
	With -R option, `cpdir' removes files and directories
	in destination that are non-existent in source.
