##### Proxy
On Linux based hosts you can set proxy server for deploy task by specifying standard environment variable - https_proxy.
E.g:
E.g:
env https_proxy=http://localhost:8080 grunt deploy

##### s3_key and s3_bucket

* s3_key : the S3Key to be used if deploying from AWS S3
* s3_bucket : the S3Bucket to be used if deploying from AWS S3

Those are an alternative to package options

##### package
Type: `String`
Default value: Package name set by package task of same target - see below.
