This is limited to cloning 100 repos at a time, the second command gets page 2

```
TOKEN=foo
ORG_NAME=developer-journey
COMPANY=IBM

$ curl -s "https://github.ibm.com/api/v3/orgs/developer-journeys/repos?access_token=TOKEN&per_page=100" | ruby -rubygems -e 'require "json"; JSON.load(STDIN.read).each { |repo| %x[git clone #{repo["ssh_url"]} ]}' 
$ curl -s "https://github.ibm.com/api/v3/orgs/developer-journeys/repos?access_token=TOKEN&per_page=100&page=2" | ruby -rubygems -e 'require "json"; JSON.load(STDIN.read).each { |repo| %x[git clone #{repo["ssh_url"]} ]}' 
```
