------------------------------------------+---------------------------------
 If you insert a USB flash drive, go to the Journal, and click on a .xol
 file on the USB drive, Sugar attempts to unpack it to ~/Library and add it
 to the OLPC home page's expanding content library.  Once you fix bug
 #1748, this works on OLPC build os852 (10.1.2 that incorporates Sugar
 0.84.16) on an XO-1.

 But then there is no way to remove the content from ~/Library and the home
 page.  Installing from USB doesn't seem to create any record in the
 Journal for the content, so there's no .xol in the Journal that you can
 Erase (which normally triggers the uninstall of the content bundle).

 To avoid this, first copy .xol to the Journal or "download" it from the
 file:/// URL of the USB flash drive; either creates a record for the .xol
 in the Journal.

 (I seem to recall that Sugar Labs has plans to unify content and
 activities that would make this and other .xol bugs go away.)
