Just make. This will build a PDF called "temp.pdf". This is the temporary pdf
which will be overwritten each time you invoke make. This is done for temporary
drafting purposes. If you are keen on the details, see Makefile
and latexrun.
Just make release. This will create a PDF with the date and time appended to
the file name. The symlink to the exam text is also updated.
Keep the .tex files shallow. Use the \input macro to include what you need.
Everything starts at master.tex.
