67 \begin{block}{Our motto}

69 \Huge A free numerical environment mostly compatible with \sc{Matlab}

76 \begin{block}{What is compatibility?}
77 \begin{itemize}
78 \item A point of much debate...
79 \pause
80 \item My personal viewpoint, shared by some: if it works in
81 {\sc{Matlab}}, it should work in Octave. If it works in Octave, it can
82 break in {\sc{Matlab}}.
83 \pause
84 \item Does this also mean it has to look exactly like {\sc{Matlab}}? Can
85 we deviate at all?
86 \pause
87 \item The perils of ``compatibility flags''
