 Replying to [comment:1 rgommers]:
 > This should really be discussed on the mailing list, preferably also
 with the authors of pysundials and scikits.ode. Could you please bring it
 up there?

 Sure. Before I do so, is there any reason I should include the authors of
 pysundials? Should I also contact the authors of python-sundials and

 As far as I can tell, pysundials hasn't been touched since 2010, and any
 updates to its Sundials wrapper from version 2.3 to version 2.4 haven't
 made it into the main branch, nor has the documentation promised on its
 web site materialized. Python-sundials hasn't been updated in over a year.
 So I have doubts that either one of these projects is under active

 Assimulo is under active development, but the nomenclature they use to
 describe their numerical solvers is confusing. For instance, they classify
 their wrappers of CVODE and Radau5 as "explicit solvers". These methods
 are both classified as implicit methods for solving ordinary differential
 equations; the only thing that's "explicit" about them is that the form of
 the ODE is an explicit ordinary differential equation, not an implicit
 ordinary differential equation (such as the classical representation of a
 DAE). Although, of the four Python modules I could find that wrap Sundials
 (i.e., Assimulo, scikits.odes, pysundials, and python-sundials), this
 module has the most documentation, the confusing nomenclature makes me
 doubt its quality.
