+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 and
+cppunit.
+
+To build the examples from the tarball use the normal recipe:
+
+ $ ./configure
+ $ make
+ $ make check
+
+If you're building from git, you'll need to use this sequence, since
+git doesn't contain configure or the generated Makefiles.
+
+ $ ./bootstrap
+ $ ./configure
+ $ make
+ $ make check
