Super Orders vs Edit Orders

Hi all

I may need to edit orders so i went looking for a mod and found

Super Orders and Edit Orders

But no where can i find anything that says exactly what they do, i am part way through the the super orders support thread (60 pages), but i was hoping some one could give me an idea of exactly what they both do

What i need is to be able to

add/remove products
Alter the shipping charge ( <-- this is the important one)

and thats all,

Any help would be appreciated

Zencart 1.3.7

Thanks for that Kelvin, I don't have to worry about the PHP 5 issue as my server is php4

Still don't know if either of them allow me to edit shipping, guess I will have to install them to find out, bah humbug

Super Orders allows you to change the price for shipping but that is about all I can figure out, you can't change the method (not that I know of!)
