The fact that you are referring to those files as 'build artifacts' should
have given you a clue it might not have to do with your version control
tool.

Again, you indicate it has to do with building, not with version control.

Maybe you should create an out-of-tree build, or export a tree from your
working copy and build there. Blow it away when your build is done. Did you
know you can export working copies (ie without contact to the server)?

If you have a system which runs on all platforms, why not use it to write
your cleanup script/app?

I hate to tell you this, but this is not the use case for the majority of
working copies...

... which you seem quite aware of.

Local changes in versioned files, yes.

I'm having an extremely hard time thinking of a good reason why this belongs
in a version control tool. I can't find any. I'm sorry.

I'm sorry if this mail is a bit harsh, but I hope the
export-for-working-copies does help you a bit...

bye,

Erik.
