Re: [Discuss-gnuradio] Best way to share/install hierarchical grc blocks?

[Porges, Donald]

Incidentally, to close out (for now) this line of conversation: I decided 
indeed to go with editing the files with a script at build/install time.  For 
anyone else who wants to go down this path, note that you must process 3 kinds 
of files:

-- the .py.xml file for the hier block
-- the .py file for any higher-level hier block that uses those blocks
-- the .py file for any sample code that uses those blocks.

Thanks again to those who answered;  I decided to go this route because I can 
do it now, without needed to modify any tools (which didn't seem 100% simple, 
which is why it hasn't already been done).
