+xfhell is a GTK+ application for the "fuzzy" digital communication mode
+known as Hellschreiber. xfhell has several different built-in fonts in
+Adobe BDF format, including a font set for Greek, and a special "short"
+font set that is 12 pixels high instead of the standard 14 of the original
+Hell fonts. Using this font set would make xfhell incompatible with other
+Hellschreiber programs, but the short fonts speed up operation and avoid
+wasted bandwidth, inherent in the original Hellschreiber design (an
+unavoidable problem of the original mechanical implementation of the mode).
+xfhell also has selectable lower baud rate operation (down to 7.6 Bd),
+which again make it incompatible with other Hellschreiber programs, but
+the lower speeds (especially combined with the 12-pixel fonts) would make
+this mode even more efficient and effective.
+
+xfhell has built-in CAT control for the FT847 and FT857 transceivers and a
+QSO logging facility similar to xpsk31. It also has a FFT-derived waterfall
+display of the incoming signal, with the ability to detect maximum signal
+level and tune the transceiver, via CAT, to the appropriate carrier
+frequency by clicking near the signal trace.
+
+By default, xfhell wants to install a directory structure in the $HOME of
+the installing user. The SlackBuild overrides this, and copies that structure
+into /usr/share/xfhell-$VERSION/.
