 python_hackrf is a Python wrapper for libhackrf and hackrf-tools.
 
 options:
-  -h, --help    show this help message and exit
+  -h, --help            show this help message and exit
 
 Available commands:
-  {info,sweep}
-    info        Read device information from HackRF such as serial number and firmware version.
-    sweep       a command-line spectrum analyzer.
+  {info,operacake,sweep}
+    info                Read device information from HackRF such as serial number and firmware version.
+    operacake           Specify either list, mode, or GPIO test option.
