"""Tests the audacity pipe.
|
|
|
|
Keep pipe_test.py short!!
|
|
You can make more complicated longer tests to test other functionality
|
|
or to generate screenshots etc in other scripts.
|
|
|
|
Make sure Audacity is running first and that mod-script-pipe is enabled
|
|
before running this script.
|
|
|
|
Requires Python 2.7 or later. Python 3 is strongly recommended.
