	i:'input',
  o:'output'
})
var resolve = require('cli-path-resolve')
var clistreams = require('cli-streams')
var through = require('through2')

var streams = clistreams(resolve(args.input), resolve(args.output))

streams.input.pipe(through(function(chunk, enc, next){
	this.push(chunk.toString().toUpperCase())
})).pipe(streams.output)
