+This repository contains support for running NetBSD PCI device drivers
+in rump kernels in Linux userspace.  Access to the devices is provided
+by the _uio_pci_generic_ Linux kernel module.
+
+See [the wiki](http://wiki.rumpkernel.org/Repo:-pci-userspace-linux)
+for information on building and using.
