=== eclib-20100711.p0 (Mariah Lenox and Leif Leonhardy, September 28th 2011) ===
 * #11354: Deleted the obsolete (Debian) dist/ directory. (May 2011)
 * Comment by Leif:
   Since (as release manager) I had to add this changelog entry, which was
   missing, and fix the files' permissions anyway, I also did little "off-ticket"
   clean-up (kind of "reviewer patch"):
   - Use `cp -p` in all copy commands, since the current umask might break
     permissions again.
   - Check exit codes of `cp` (and `strip`) and all other important commands.
   - Minor cosmetic clean-up, such as replacing `uname` by "$UNAME" and  else-if
     ladders by `elif`.
