一个简单实用的，可访问zookeeper的C++标准API接口及各种访问操作工具

zookeeper's c++ api and access tool:zk_create, zk_get, zk_update, zk_list, zk_delete, zk_get_acl, zk_set_acl

[append]°¢[set]°¢[remove] can be set°£default is append. -o: output file, default is stdout -r: recursive to set child acl. -v: node's version -h: help

=============================================================== zk_lock: Test for lock zookeeper node. ./zk_lock -H host:port -n node [-d data] [-f data file] [-o output file] [-a usr:passwd] [-l privilege]

-H: zookeeper's host:port

-n: node name for lock.

-p: prex for lock. default is [lock].

-a: auth user's user:passwd. it can be multi.

-l: node's acl. it can be multi. it's value can be:

all               :  any privilege for any user;

self              : any privilege for creator; 

read              : read for any user;

user:passwd:acrwd : digest auth for [user] with [passwd], 

      admin(a), create(c), read(r), write(w), delete(d)

-m: watch master node
