Component:  ports        |    Version:
 Keywords:               |       Port:  nethack
-------------------------+--------------------------------
 I removed and reinstalled all my ports (including Nethack) after upgrading
 to Mavericks from Mountain Lion, some months ago. I recently resumed a
 saved game and, ultimately, died (YASD). While it was gratifying to see
 that I made the top score, it was in fact the ONLY score--my prior
 ascensions were no longer on display!

 Fortunately TIme Machine was able to mitigate this disaster ( :) ), but it
 would be nice if the port, when installed, renamed the "record" and
 "logfile" files in share/nethackdir to "record.orig" and "logfile.orig",
 respectively, then copied to the non-suffixed names only if they did not
 already exist (similar to what is done for config files for other ports).
 That would prevent the files from being removed when the port is
 uninstalled/upgraded, and prevent them from being clobbered on reinstall.
