[bug#29768] [PATCH 0/5] Graphite

[Ricardo Wurmus]

Hi Guix,

this patch series adds the Graphite graphing system for visualising and
monitoring time series data.

I haven't tested it much because it requires a wsgi service.  What's weird is
that it installs a file
"lib/python2.7/site-packages/graphite/local_settings.py.example", which a user
is supposed to edit before-hand.  It contains site-specific settings.  Since
we don't want people to feel tempted to change the file in the store, a user
could also provide settings by prepending a directory containing the settings
to the PYTHONPATH.

I'll play with this a little and then write a service for Graphite.

Ricardo Wurmus (5):
  gnu: Add python-txamqp.
  gnu: Add python-django-tagging.
  gnu: Add python-whisper.
  gnu: Add python2-carbon.
  gnu: Add python2-graphite-web.
