export ISO split says it takes bytes argument but really takes MB
When exporting an ISO of yum content, you can set iso_size to set how big you want the ISO to be. This is in MB, but some places inside the code say bytes. This leads to confusion :)
It is a little redundant, but please make the "in megabytes" part bold in the doc as well, just for additional clarity. I saw the byte math in the doc and incorrectly assumed bytes.
