| # 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. |
