xo-get update

[Mikus Grinbergs]

What would be really nice to have would be a "bullet-proof" way to 
install [and remove] activities (besides using Browse to load the 
Activities into the Journal).

Ages ago on my G1G1, I had unzipped sonata.xo to my olpc/Activities 
directory.  But it would not initialize.  Given the announcement of 
'xo-get', I erased what I had unzipped and tried 'xo-get.py install 
Sonata'.  That got an error, telling me "maybe already installed". 
Then I tried 'xo-get.py remove Sonata'.  That failed.  Again trying 
'xo-get.py install Sonata' had same error as earlier.  Oh well.
