Now it's allow passing command line arguments to task now,the task
macro is changed,it must have an argument vector now:
(task :deploy deploy a file to remote machines
[file]
(scp (file) /home/user1))
And run with
clojure controls.clj deploy release.tar.gz
The release.tar.gz will be used as file argument for scp macro.
clojure-control is still on development,any suggestion welcomed.

1.What is clojure-control?
The idea came from node-control(https://github.com/tsmith/node-
control).
Define clusters and tasks for system administration or code
deployment, then execute them on one or many remote machines.
Clojure-control depends only on OpenSSH and clojure on the local
control machine.Remote machines simply need a standard sshd daemon.
2.Quick example
Get the current date from the two machines listed in the 'mycluster'
config with a single command:
(ns samples
(:use [control.core :only [task cluster scp ssh begin]]))
;;define clusters
(cluster :mycluster
:clients [
{ :host a.domain.com :user alogin}
{ :host b.domain.com :user blogin}
])
;;define tasks
(task :date Get date
(ssh date))
;;start running
(begin)
If saved in a file named controls.clj,run with
java -cp clojure.jar:clojure-contrib.jar:control-0.1-SNAPSHOT.jar
clojure.main controls.clj mycluster date
Each machine execute date command ,and the output form the remote
machine is printed to the console.Exmaple console output
Performing mycluster
Performing date for a.domain.com
a.domain.com:ssh: date
a.domain.com:stdout: Sun Jul 24 19:14:09 CST 2011
a.domain.com:exit: 0
Performing date for b.domain.com
b.domain.com:ssh: date
b.domain.com:stdout: Sun Jul 24 19:14:09 CST 2011
b.domain.com:exit: 0
Each line of output is labeled with the address of the machine the
command was executed on. The actual command sent and the user used to
send it is displayed. stdout and stderr output of the remote process
is identified as well as the final exit code of the local ssh
command.
3.How to scp files?
Let's define a new task named deploy
(task :deploy scp files to remote machines
(scp (release1.tar.gz release2.tar.gz) /home/alogin/))
Then it will copy release1.tar.gz and release2.tar.gz to remote
machine's /home/alogin directory.
