## dustmite.py is the main tooltron server |
|
| 5 |
# It connects to the civicrm database of mysql and sends commands to |
|
| 6 |
# the cardbox and tools. It must be connected over usb to the card |
|
| 7 |
# reader, and the two arguments specify the devices to use for the |
|
| 8 |
# serial communication to the card and tool boxes. |
|

# This script requires the modules seen below, which may not be |
|
| 11 |
# present by default |
