usrp_rx_hrpt.py
+---------------
This GUI script will receive HRPT RF, demodulate, synchronize, and deframe
HRPT minor frames into a file. The file stores a series of 11090 word,
16-bits per word corresponding to the HRPT minor frame format (only the
lower 10-bits per word are significant.)

+---------------

+This GUI script operates like usrp_rx_hrpt.py, but reads from a pre-captured

+usrp_rx_hrpt_nogui.py
+---------------------
+
+This non-GUI script operates without a display and requires that all parameters
+be set in the configuration file prior to running. It has no command-line
+parameters, and works identically to the GUI scripts.
