I wonder if you could just use rsync (without timestamp checking) for this? If your:
- documentation set isn't so large that temporarily having a second set causes problems - configuration is such that output stays the same until your source or Doxygen versions change You could keep the real/stable output copy in one location, generate a temporary copy into a separate location, then rsync without timestamp checking (may need to use checksum mode?) It might be possible to accomplish something similar if you keep the output in git or another vcs if they're capable of preserving timestamps, but I haven't looked into that.
