Hi Matthias; that project ended almost two years ago and did not have
enough funding to complete.
In the last couple of weeks Andrea has taken an interest in the
process API defined by that project and has recast it to allow set of
names (rather then just one). With that in mind I think the parsing
code may need to be updated before it is fit for use.
As for the specific parse error; we would welcome a contributor such
as yourself to look into the problem and supply a patch. Since the
module is unmaintained could actual adopt the module yourself.
