#[cfg_attr(not(feature = "library"), entry_point)]
pub fn execute(
    _deps: DepsMut,

' Modified by Jason Kerwin (www.jasonkerwin.com) on 20 February 2018:
    ' Takes out extra text that printed in the title line
    ' Switches titles to \frametitle{} instead of including them on the \begin{frame} line (sometimes helps with compiling)
    ' Changes the image names to remove original filename, which might have spaces
    ' Removes "\subsection{}" which was printing before each slide
'NB you must convert your slides to .ppt format before running this code
