"   Bugs: For some reason this won't work if there are \begin{document}
"   commands in the file, so I just split up the LaTeX file as follows:
"   
"       \documentclass{article}
"       \usepackage{sagetex}
"       
"       \begin{document}
"       \input{body}
"       \end{document}
"
"   Then editing body.tex works ok.

	syntax clear
