[dev-context] updated Ubuntu edgy texlive+context backports

[Sanjoy Mahajan]

I just updated the Ubuntu edgy backports of the texlive packages (for
i386) and have been running them on my feisty laptop for half a day.
The 'context' package provides version 2007.04.17 12:51.

They are recompilations of the latest Ubuntu gutsy (7.10) packages,
which are Norbert's latest Debian packages with a couple additions.  Let
me know if you have problems.

To use the packages, add these lines to your /etc/apt/sources.list :

  deb     http://web.mit.edu/download/sanjoy/texlive-backports/ edgy/
  deb-src http://web.mit.edu/download/sanjoy/texlive-backports/ edgy/

Then

 apt-get update
 apt-get install cm-super texlive-fonts-recommended \
                 context context-nonfree context-doc-nonfree

('cm-super comes from the universe repositories)

Sorry, no dapper (6.06) backports yet!  A few tricky package-version
obstacles remain.
