I'm trying to use the sagetex style file in LaTeX. After trying to process the example.tex file provided with sagetex, I get error messages in the log that say to "Run Sage on example.sagetex.sage".
On my OS X system, Sage is installed as a clickable .app. After I start the app, I know how to start a Terminal command session of Sage by using the right-click menu from the Sage icon in the dock.
But how do I process such a .sage file in there?
