+Driving GetDP from cim.py
+-------------------------
+cim.py and GetDP are exchanging the following ONELAB variables:
+  angularFreqRe - the real part of the frequency
+  angularFreqIm - the imaginary part of the frequency
+  x()           - the solution vector of the linear system
+  b()           - the right hand side (RHS) of the linear system
+  imposeRHS     - flag signalling if an other RHS should be imposed
+  doPostpro     - flag signalling if only a post-processing should be done
+  doApply       - flag signalling if x() should be applied to the linear system
+  fileName      - name of the post-processing file
+More information can be found in bin/solver.py. Furthermore, examples are
+provided in example/maxwell_sibc/ and example/maxwell_linear/.
