# tex2slide.sh
#
# A simple shell/Apple script to copy text from Keynote, compile it using 
# pdflatex, and paste it back into Keynote as a pdf snippet. As is, the 
# script works for Keynote, but it should work for Powerpoint and other
# applications by replacing Keynote below with another name.
#
# To create MacOS app, execute:
#  mkdir -p Tex2Slide.app/Contents/MacOS
#  cp tex2slide.sh Tex2Slide.app/Contents/MacOS/Tex2Slide
#  chmod +x Tex2Slide.app/Contents/MacOS/Tex2Slide
