+#
+#  It's simple enough to figure out how this works.
+#  If not, then you can ask me at stripconfig@goodmis.org
+#
+# What it does?
+#
+#   If you have installed a Linux kernel from a distribution
+#   that turns on way too many modules than you need, and
+#   you only want the modules you use, then this program
+#   is perfect for you.
+#
+#   It gives you the ability to turn off all the modules that are
+#   not loaded on your system.
+#
+# Howto:
+#
+#  1. Boot up the kernel that you want to stream line the config on.
+#  2. Change directory to the directory holding the source of the
+#       kernel that you just booted.
+#  3. Copy the configuraton file to this directory as .config
+#  4. Have all your devices that you need modules for connected and
+#      operational (make sure that their corresponding modules are loaded)
+#  5. Run this script redirecting the output to some other file
+#       like config_strip.
+#  6. Back up your old config (if you want too).
+#  7. copy the config_strip file to .config
+#  8. Run "make oldconfig"
+#
+#  Now your kernel is ready to be built with only the modules that
+#  are loaded.
+#
+# Here's what I did with my Debian distribution.
+#
+#    cd /usr/src/linux-2.6.10
+#    cp /boot/config-2.6.10-1-686-smp .config
+#    ~/bin/streamline_config > config_strip
+#    mv .config config_sav
+#    mv config_strip .config
