+This directory (and the resulting tarball) contains a build tree with
+examples, Makefiles, etc that demonstrate how to write signal
+processing blocks for the GNU Radio system. This directory is
+intentionally distributed separately from the unified tarball of the
+rest of GNU Radio in order to avoid problems for people who have begun
+to write blocks with a modified copy of gr-howto-write-a-block.
This package requires that gnuradio-core is already installed. It
also depends on some GNU Radio prerequisites, such as boost.
