+	<longdescription>
+		The RISC-V Proxy Kernel, pk, is a lightweight application execution environment that can host
+		statically-linked RISC-V ELF binaries. It is designed to support tethered RISC-V implementations
+		with limited I/O capability and thus handles I/O-related system calls by proxying them to a host
+		computer.
+
+		This package also contains the Berkeley Boot Loader, bbl, which is a supervisor execution
+		environment for tethered RISC-V systems. It is designed to host the RISC-V Linux port.
