Contributing is more involved than simply downloading a profile. I think you |
| 65 |
have to use the TaxiDB API: |
| 66 |
|
| 67 |
http://sourceforge.net/p/openicc/taxi/ci/master/tree/docs/api_doc.txt |
| 68 |
|
| 69 |
I you are interested then you can contact the OpenICC project to ask for |
| 70 |
