+ "Qucs-S is a spin-off of the Qucs cross-platform circuit
+simulator. The \"S\" letter indicates SPICE. The purpose of the Qucs-S
+subproject is to use free SPICE circuit simulation kernels with the
+Qucs GUI. It merges the power of SPICE and the simplicity of the Qucs
+GUI. Qucs intentionally uses its own SPICE incompatible simulation
+kernel Qucsator. It has advanced RF and AC domain simulation features,
+but most of the existing industrial SPICE models are incompatible with
+it. Qucs-S is not a simulator by itself, but it requires to use a
+simulation backend with it. The schematic document format of Qucs and
+Qucs-S are fully compatible. Qucs-S can be used with the following
+@item Ngspice is recommended to use. Ngspice is powerful
+mixed-level/mixed-signal circuit simulator. The most of industrial
+SPICE models are compatible with Ngspice. It has an excellent
+performance for time-domain simulation of switching circuits and
+@item XYCE is a new SPICE-compatible circuit simulator written by
+Sandia from the scratch. It supports basic SPICE simulation types and
+has an advanced RF simulation features such as harmonic balance
+@item SpiceOpus is developed by the Faculty of Electrical Engineering
+of the Ljubljana University. It is based on the SPICE-3f5 code.
+@item Backward compatible with Qucsator.
