From: jcorgan <jcorgan@221aa14e-8319-0410-a670-987f0aec2ac5>
Date: Tue, 18 Sep 2007 18:59:00 +0000
Subject: Merge r6461:6464 from jcorgan/t162-staging into trunk.
* Final gr.top_block and gr.hier_block2 implementation inside
gnuradio-core/src/lib/runtime
* Implementation of gr.hier_block2 versions of all the old-style blocks
in blks. These live in blks2.
* Addition of gr.hier_block2 based versions of gr-wxgui blocks
* Conversion of all the example code in gnuradio-examples to use this
new code
* Conversion of all the gr-utils scripts to use the new code
The OFDM examples and related hierarchical blocks have not yet been
converted. Code in the rest of the tree that is outside the core
and example components has also not yet been converted.
