+# Part of the dgrp-1.9.35 PKGBUILD from Arch Linux AUR
+# http://aur.archlinux.org/
+
+# If you remove this script your package will not auto rebuild 
+# and your hardware will stop working after the next kernel upgrade.
+
+# Purpose: Automatically build and install this package on the next login
+# after pacman removes it on kernel upgrade. 
+# Every package that needs to be autorebuilt should have a shell script
+# like this one. All you need is a PKGBUILD and a sense file to tell
+# when the package is missing.
+
+# This shell script can be easily adapted to any PKGBUILD. As an alternative
+# you can look into "DKMS" Dynamic Kernel Module Support.
+
+# To launch, add this to any user's profile or the system profile.
+# The preferred user is the one most likely to log on after an upgrade.
+# sudo must be installed and configured. Each user expected to rebuild packages
+# must be added to the wheel group (usermod -G).
+
+# for install_group in `groups`; do
+#   if [ "$install_group" = "wheel" ]; then
+#     find ~/pkg -type f -perm /400 -name "autorebuild-*.sh" -exec sh {} \;
+#     break
+#   fi
+# done
+
+# This presumes you have neatly placed all your packages into ~pkg.
+
+# (Note: the multi user aspect has yet to be tested)
+
+# For multiple users you can use a standard folder set to be world writable.
