Alright, I’ve just had to edit an existing wsp 😐
I won’t go into the why and wherefores, suffice to say that I decided that the easiest way to achieve my end was to extract the contents, edit the necessary XML file and repack the cab.
Now I didn’t feel like writing a ddf and using MAKECAB.EXE for this quick hack, so I had a quick Google Live Search ;o) and found CabPack 1.4 sure it was last written in 1999 but it works, it’s free and the UI is dead easy to use.
That is the total extent of the UI, there is easy to follow documentation provided too.
