To install this snapshot of Open edX devstack (no network access required):

1. Copy the entire "devstack_snapshot" directory to your computer.  You'll
   need about 35 GB free (9 GB for the copied files and 26 GB more for the
   subsequent installation.

2. Unmount the flash drive, remove it, and return it to the workshop staff
   so someone else can use it.
