The amount of support work multiplies by a lot when you have so many game wrappers.
The workload was greatly reduced by moving all major functions into winewrap.shlib - changes there only need to be made once, and then I can apply it to all wrappers with a single command. Aside from that, I have a set of scripts to speed things up even more, whether it's updating start scripts or documentation or whatever. Also 'sed' is very useful for things like that :p
The biggest hassle now when updating everything is having to go over all of the release posts with the new file sizes/SHA256 hashes/update info. I have a script to take care of much of that too but it's still a lot of copy+pasting... I'm tempted to move all the file size/checksum info into a single post to make it easier.
