SageMathCloud LaTeX Support

SageMathCloud allows you to run LaTeX online in a full Linux environment. It supports the standard compilers, latexmk, and a large number of libraries are pre-installed. On top of that, SageTeX adds the capability of running SageMath code right inside of TeX files to seamlessly embed code, results, formulas and plots.

The directory sagetex shows how to run SageMath inside a document, and multiple-files demonstrates how to setup a larger LaTeX document with multiple source files.
