xpsk31 is a GTK+ graphical version of lpsk31, using the same basic 
signal decoding and encoding engine but controlled by the user via 
the GUI. In addition it has a FFT-derived "waterfall" display of 
the incoming signal and a "magniphase" display that shows the magnitude, 
phase and frequency error of the psk31 signal. It has similar QSO 
logging facilities and CAT control, for the FT847 and FT857 transceivers, 
which can be used to tune the transceiver to the appropriate carrier 
frequency by clicking on a signal trace.

By default, xpsk31 wants to install a config file into the installing
user's home directory. This has been redirected to 
/usr/share/xpsk31-$VERSION/xpsx31rc and can be installed
from there into ~/xpsk31/.
