Some people would just do a plain shell copy of the file and then hg add the "new" file. I prefer to use an actual SCM copy because I am re-using portions of the original file. If it turns out there is a bug in the boilerplate that I copied the "hg copy" does leave a tenuous link back to the source which would still have the same bug. If I just used regular copy and then hg add then that link is broken completely.
