There are 3 parts to wyBuild:
- wyBuild itself: This part is not open source. You use wyBuild to manage and build your update patches. This is what you're buying when you purchase a license.
- wyUpdate: This is the updater you include with your app. This is completely open source.
- the AutomaticUpdater: this is an optional component you can include with your app. This is also open source.
So if you don't mind manually building your update patches, then by all means just use wyUpdate and the AutomaticUpdater. But trust me, you don't want to build the update by hand.
Use wyBuild to simplify everything.
Does that make sense?
