Hi Steve, the patch introduces new problems, e.g. the files are not created if --index is given without --gmapsupp. Also --no-tdbfile doesn't work with --nsis (I think this combination should cause an IllegalArgumentException) The need for the --tdbfile option with --index is documented, so maybe it would be better to fix the creation of the *.nsi file.

The files are created if I add option --tdbfile or when I remove --gmapsupp. This is quite confusing. I've attached a patch to fix this, please review and commit if you think it is okay. Gerd
