The edits to these files end up breaking the scripts ... besides needing a change to the unzip line:

```
unzip latest.zip
```

Somehow we need to be extract the name of the image and changes files after unzipping. For example when I unzip latest.zip, I get a directory with the name `Pharo-1.0-10517-rc4dev10.04.1` and the image and changes files are named:

```
Pharo-1.0-10517-rc4dev10.04.1.changes
Pharo-1.0-10517-rc4dev10.04.1.image
```

So presumably these names will change without warning ... if you could update the scripts to match whatever scheme  you are using (for each of the platforms ... I haven't looked to see if they even follow the same pattern ... I'll accept the pull request ... thanks!
