+% Include only certain frames - this speeds up compilation
+% The frames to be included need to be labeled, by using ERT
+% as [label=LABELNAME] (no backslashes or {})
+%\includeonlyframes{currentt}
+
+% To make a printable handout (one page per frame), pass
+% the handout option to the doc class (Layout menu)
+
+% For good fonts in PDFs, use pslatex fonts (Layout menu)

+
+% Theme configuration.  I've basically built a custom theme out of 
+% Warsaw, adding infoline and changing the nav. symbol bar
+
+% Warning: the commands below are order-sensitive!
+
+% load the infolines theme, b/c I want the headline Warsaw 
+% uses (split), but the footline from infolines.
+% In the document body, these will be deactivated for the title and
+% turned on later
+\useoutertheme{infolines}
+% Main theme
+\usetheme{Warsaw}
+% Adjust the color for the center (title) box to be that of
+% infolines, which Warsaw changes
+\setbeamercolor*{title in head/foot}{parent=palette secondary}
+
+% Define a minimal set of navigation symbols
+\defbeamertemplate*{navigation symbols}{minmal}
+{%
+  \hbox{%
+    \hbox{\insertframenavigationsymbol}
+    \hbox{\insertdocnavigationsymbol}
+    \hbox{\insertbackfindforwardnavigationsymbol}%
+  }%
+}
+% activate the minimal navbar
+\setbeamertemplate{navigation symbols}[minimal]
+
+%%%%% HACK %%%%%
+% I started getting errors because LyX is emmitting a color 'none'
+% call, which confuses xcolor.  I'm defining 'none' to be black here.

+Some things to fix in a future version:
+\end_layout
+
+\begin_layout Standard
+- trim a bit of time
+\end_layout
+
+\begin_layout Standard
+- add more about ipython and my own python work, reduce that of others
+\end_layout
+
+\begin_layout Standard
+- add a final python pros/cons, esp.
+ the cons part.
+ It will make things more balanced.
+\end_layout
+
+\begin_layout Standard
+- the PDE part repeats a bit the 'python benefits' which were already pounded
+ on.
