Our current pmdoc could be much improved:

• add a description of what is rudix and what will happen during install in the first step of the wizard
• use a custom background for rudix
• generate the new 10.5+ flat packages
• present in the end of install how to use the just installed package

Using new flat packages makes it not necessary to have a dmg wrapper around packages, we should look into this.

the one we have already generate flat packages.
