Jigdo will then download a copy of the .jigdo file using wget and then prompt you for any previous images you have to base the download from.
If you already have a previous version of the CD you are downloading, jigdo can re-use files on the old CD that are also present in the new image, and you do not need to download them again. Mount the old CD ROM and enter the path it is mounted under (e.g. `/mnt/cdrom'). Alternatively, just press enter if you want to start downloading the remaining files.
Here you can point Jigdo to an existing .iso file (ie; ~/dapper-install-i386.iso) or a previously burned copy of such (ie; /media/cdrom)
