# A slides file should populate the variable slides with
# a list of tuples.  Each tuple should have:
#
#	- Slide content
#	- User data
#	- Canvas width
#	- Canvas height
#
# Slide content can be a string, a list of strings,
# a function returning one of those, or a generator
# yielding strings.  The user data should be a dictionary or
# None, and is both used to communicate options to the
# renderer and to pass extra options to the theme functions.
#
# A function-based slide content will be passed a renderer object.
# Renderer is an object similar to a cairo.Context and
# pangocairo.CairoContext but has its own methods too.
# The more useful of them here are put_text, put_image, and
# set_allocation.  See their pydocs.

Hi Erik,

I'm planning to visit The Hague in January, mostly to
meet Bahman, and hopefully to work with you.  We
can discuss / hack on interpolation, OpenType GX,
or really anything fonts &amp; Python.  Would you be
interested in that?  I'm thinking some time the week
of January 18th.

Hi Behdad,

That's unexpected :) I have time that week and we
can meet earlier in the week.  I do have some
academic obligations on Thursday and Friday and
the Type and Media open day that Saturday.

Would that work for you?

Hi Behdad,

I hope to see you next week! It’s above freezing

Just is at the academy on Wednesday and would like
to meet you.  Frederik Berlaen lives in Gent, Belgium
and can come up on Friday or Thursday.
