I like this change in header include structure. Most of the projects I work on
do it this way, and it makes a lot of sense. Because this will be a change
that impacts just about everyone doing C++ development using GNU Radio, I think
-if possible- it would be good to keep the "gr_<name>.h" headers around, but
all they do is 2 things:
1) print out a #warning about being deprecated, and to instead use
"blocks/<name>.h" -- or, whatever makes sense for such a message; and
2) #include "blocks/<name>.h" so that the user's code still compiles as before
That way, we benefit from the new header include structure, but aren't totally
screwed if we've forgotten to use it. And, somewhere down the road after an
appropriate amount of time, the "gr_<name>.h" headers can be removed entirely,
if desired, because everyone has been well warned. I hope something along this
line can be done.
