   7 # This will install the somefile.conf.sample and automatically copy to
   8 # somefile.conf if it doesn't exist. On deinstall it will remove the
   9 # somefile.conf if it still matches the sample, otherwise it is
  10 # kept.

  12 # This replaces the old pattern:
  13 #  @unexec if cmp -s %D/etc/pkgtools.conf %D/etc/pkgtools.conf.sample; then rm -f %D/etc/pkgtools.conf; fi
  14 #  etc/pkgtools.conf.sample
  15 #  @exec [ -f %B/pkgtools.conf ] || cp %B/%f %B/pkgtools.conf
