just a question. the virtual machine from openlane, uses travis ci. is it too complicated to make a folder for jenkins? I use jenkins more. of course it doesn't have to be now, it may be later.

It sort of just happened, and so far we didn't have much trouble with using travis CI for testing, and there is no pressing need to move away from it. But, if you feel that Jenkins will bring more to the table, feel free to migrate the configuration and test scripts and submit a PR.
