Installer.app feedback

[Frederico Muñoz]

Hello,

I have began to write an installer application (hereafter Installer or 
Installer.app). I have some ideas but I need some feedback on some things.

The main idea - and what is actually already done - is this: for each packaging 
format there is a bundle. I have a "Package" protocol that defines what each 
bundle should provide. The program initially asks each bundle if it can handle 
the package ((BOOL) handlesPackageInPath: (NSString *) pkgPath) and as soon as 
some bundle says yes the bundles's class is responsible to return the other 
info. The info that should be return is also in the protocol and is by now 
rather general: Description, Version, Name, Author, Sizes. This is so because 
the information that a package can return can vary between each packaging 
format.

The interface itself is made of a NSTabView that has  Information/License/List 
of Files tabs.

I was thinking that maybe another tab (something like "Specific Package 
Information") should be available and that would be the responsability of the 
bundle to add information there. This would allow extra info that can't be 
generalized to be presented nonetheless (things like Section, dependencies, 
etc).

I would greatly appreciate comments, suggestions and general advices regarding 
this. I am asking this before actually showing any code because this sort of 
things could change the way the app is designed.

Best Regards,

Frederico Muñoz
