# A sample context menu handler. |

# |
| 5 |
# To demostrate: |
| 6 |
# * Execute this script to register the context menu. |
| 7 |
# * Open Windows Explorer, and browse to a directory with a .py file. |
| 8 |
# * Right-Click on a .py file - locate and click on 'Hello from Python' on |
| 9 |
# the context menu. |
