Getting started with the 12.04 Documentation Stable Release Update

[Jack Fromm]

Last night I said I would work on Chapter 5.  That went very quickly, so 
I went on to Chapters 7 and 8 too (printing-scanning.xml and 
managing-applications.xml).

I have a question about Chapter 8.  The current Raring/Saucy version 
that we're backporting says that Xubuntu has two package managers, USC 
and apt-get.  Do we want to put Synaptic back in since it was still 
there in Precise or leave it out so as not to encourage people to use it?
