+The GNU Radio Utility Etcetera Library, a collection of low-level routines
+to avoid dependencies on the full GNU Radio core or other libraries.
+
+Over time, some code from libgnuradio-core, libpmt, libmblock, libusrp,
+and libusrp2 will migrate here, to avoid duplication of code and simplify
+dependencies.
+
+By design, this library will not have dependencies on any other part
+of GNU Radio, but may have external dependencies such as Boost.
