[Discuss-gnuradio] Illegal sub-command when installing

[Jason Matusiak]

Attempted to install gnuradio on a tablet and had a problem with 
rtl-sdr.  I blew away my install directory as well as .pybombs.  Now 
when I run the recipe add command from the instructions, I get and error:
PyBOMBS.recipes - ERROR - Illegal sub-command: `add'
PyBOMBS.recipes - ERROR - Valid sub-commands are: 
list-repos,add,list,update,remove

What is the issue with add?  And is the fact that there are two 
different types of "tics" around the word "add" in the error message 
telling in some way?
