usage: xschem [options] [schematic | symbol ]
Options:
  -h  --help          print this help
  -n  --netlist       do a netlist of the given schematic cell
  -v  --version       print version information and exit.
  -V  --vhdl          set netlist type to VHDL
  -S  --simulate      run a simulation of the current schematc file 
                      (spice/Verilog/VHDL, depending on the netlist 
                      type chosen).
  -w  --verilog       set netlist type to Verilog
  -i  --no_rcload     do not load any xschemrc file
  -t  --tedax         set netlist type to tEDAx
  -s  --spice         set netlist type to SPICE
  -3  --a3page        set page size for pdf export to A3
  -x  --no_x          dont use X (only command mode)
  -z  --rainbow       use a raibow-looking layer color table
  -W  --waves         show simulation waveforms
  -f  --flat_netlist  set flat netlist (for spice format only)
  -r  --no_readline   start without the tclreadline package ( this is
                      necessary if stdin and stdout are to be redirected
                      for example to /dev/null).
  -c  --color_ps      set color postscript
  --rcfile <file>     use <file> as a rc file for startup instead of the
                      default xschemrc.
  -p  --postscript    export pdf schematic
      --png           export png schematic
      --svg           export svg schematic
  -q  --quit          quit after doing things (no interactive mode)
  -l <file>
  --log <file>        set a log file
  -d <n>
  --debug <n>         set debug level:  1,  2,  3,..  C program debug
                                       -1, -2, -3...  TCL frontend debug

xschem: interactive schematic capture program

Example:   xschem counter.sch
the schematic file `counter' will be loaded searching in the
list of library paths provided by TCL variable XSCHEM_LIBRARY_PATH
This variable is set in user or system xschem startup file 
(<install root>/share/xschem/xschemrc or ~/.xschem/xschemrc)
