There was a problem hiding this comment. I know there's a thing with copying the report renderer files around, but is it possible to support this in the top-level There was a problem hiding this comment. also need a license file in parallel to it, and ideally a readme that says the source commit and lists the modifications made There was a problem hiding this comment. I'll do these as a followup. It adds too much complexity to the roll right now. |
