OPEN BUGS:

* return value:
* pole-zero analysis
When ngspice is called in batch mode it returns 1 even if the simulations
are run. The problem arises when there is a .control section but no
.print, .plot or .fourier lines. Ngspice outputs:
The pole-zero (.pz) analysis, which still uses the original spice3f5
algorithms, does not give correct results for all tested input files.
The effort to correct that issue seems to be large.
Note: No ".plot", ".print", or ".fourier" lines; no simulations run
and exits returning 1.
Workaround: add -r <dummyfile> to the command line to avoid this.

* voltage (and current) controlled switches need better timing
The controlled switches (SW, CSW), which still stem from the original
spice3f5 implementation, sometimes lead to wrong results when on and off
ramp times differ considerably.
