+# This script is part of the ChromeOS package binary search triage process.
+# It should be the first script called by the user, after the user has set up
+# the three necessary build tree directories (see the prerequisites section of
+# README.cros_pkg_triage).
+#
+# This script requires two arguments.  The first argument must be the name of
+# the board for which this work is being done (e.g. 'daisy', 'lumpy','parrot',
+# etc.).  The second argument must be the name or IP address of the chromebook
+# on which the ChromeOS images will be pushed and tested.
+#
+# This script sets up a soft link definining /build/${board} to point
+# to the working build tree, for the binary search triags process.  In
+# addition, this script generates two other scripts, common.sh,
+# which generates enviroment variables used by the other scripts in the
+# package binary search triage process; and ${board}_cleanup.sh,
+# which undoes the various changes that this script performs, returning the
+# user's environment to its original state.
+#
+
+# Set up basic variables.
