[ale] rpm's src vs binary and the confusion

Seems to me a %pre script should be just that - used ONLY prior to
installation. Other scripts should be installed as part of the application
and thus NOT part of the %pre section.

Keep it simple.

You just put the script itself in the %pre section as bare code. Be sure to
NOT include the #!/bin/sh header line.

If that same script is used elsewhere, use the %files section and handle
from SOURCE.
