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.
