+This port is an emulation layer to port linux device drivers to FreeBSD,
+mostly oriented to USB device drivers where FreeBSD support is weaker.
+It contains:
+- a set of headers with declarations for entities used in the Linux kernel;
+- a compatibility library (in source form) mapping [part of] the linux kernel
+  APIs to equivalent FreeBSD APIs;
+- a template for character device drivers.
+Ideally, the porting of a linux driver should be as simple as downloading
+the linux driver sources, writing a simple Makefile.kmod, and running
+"make -f Makefile.kld" to produce your driver.ko.
