+# This script is used to configure the linux kernel.
+#
+# It was inspired by the challenge in the original Configure script
+# to ``do something better'', combined with the actual need to ``do
+# something better'' because the old configure script wasn't flexible
+# enough.
+#
+# Please send comments / questions / bug fixes to raymondc@microsoft.com.
+#
+# Each line in the config file is a command.

+# 050793 - use IFS='@' to get around a bug in a pre-version of bash-1.13
+# with an empty IFS.
+
+#
+# Make sure we're really running bash.
+#
+# I would really have preferred to write this script in a language with
+# better string handling, but alas, bash is the only scripting language
+# that I can be reasonable sure everybody has on their linux machine.
